I'm a beginner in Magento and I try to create a page on which I get all orders of a customer payed with a custom payment method.

Now, the page work but I want the page to looks like a real customer admin page, and to display the navigation on the left.

My custom layout (devis_index_index.xml)

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
 <referenceContainer name="content">
 <block class="OpsoneKgAdminBlockIndex" name="devis_index_index" template="Opsone_KgAdmin::index.phtml" />
 </referenceContainer>
</page>

and my template (index.phtml)

<?php $items = $this->getOrderCollection(); ?>

<div class="o-main-box">
 <?php if ($items != 'disconnect' && count($items)): ?>
 <div class="table-wrapper orders-history">
 <table class="data table table-order-items history" id="my-orders-table">
 <caption class="table-caption"><?= /* @escapeNotVerified */ __('Orders') ?></caption>
 <thead>
 <tr>
 <th scope="col" class="col id"><?= /* @escapeNotVerified */ __('Devis #') ?></th>
 <th scope="col" class="col date"><?= /* @escapeNotVerified */ __('Date') ?></th>
 <?= /* @noEscape */ $block->getChildHtml('extra.column.header') ?>
 <th scope="col" class="col shipping"><?= /* @escapeNotVerified */ __('Ship To') ?></th>
 <th scope="col" class="col total"><?= /* @escapeNotVerified */ __('Total du devis') ?></th>
 <th scope="col" class="col status"><?= /* @escapeNotVerified */ __('Status') ?></th>
 <th scope="col" class="col actions"><?= /* @escapeNotVerified */ __('Action') ?></th>
 </tr>
 </thead>
 <tbody>
 <?php
 foreach ($items as $_order) : ?>
 <tr>
 <td data-th="<?= $block->escapeHtml(__('Order #')) ?>" class="col id"><?= /* @escapeNotVerified */ $_order->getRealOrderId() ?></td>
 <td data-th="<?= $block->escapeHtml(__('Date')) ?>" class="col date"><?= /* @escapeNotVerified */ $block->formatDate($_order->getCreatedAt()) ?></td>
 <td data-th="<?= $block->escapeHtml(__('Ship To')) ?>" class="col shipping"><?= $_order->getShippingAddress() ? $block->escapeHtml($_order->getShippingAddress()->getName()) : '&nbsp;' ?></td>
 <td data-th="<?= $block->escapeHtml(__('Order Total')) ?>" class="col total"><?= /* @escapeNotVerified */ $_order->formatPrice($_order->getGrandTotal()) ?></td>
 <td data-th="<?= $block->escapeHtml(__('Status')) ?>" class="col status"><?= /* @escapeNotVerified */ $_order->getStatusLabel() ?></td>
 <td data-th="<?= $block->escapeHtml(__('Actions')) ?>" class="col actions">
 <a href="<?= $block->getUrl('sales/order/view', ['order_id' => $_order->getRealOrderId()]); ?>" class="action view">
 <span><?= /* @escapeNotVerified */ __('Voir le devis') ?></span>
 </a>
 </td>
 </tr>
 <?php
 endforeach;
 ?>
 </tbody>
 </table>
 </div>
 <?php elseif ($items != 'disconnect' && !count($items)) : ?>
 <div class="message info empty"><span><?= /* @escapeNotVerified */ __('Vous n'avez aucun devis en cours') ?></span></div>
 <?php else: ?>
 <div class="message info empty"><span><?= /* @escapeNotVerified */ __('Merci de vous connecter pour accéder à vos devis') ?></span></div>
 <?php endif ?>
</div>

Thank you :)

In your devis_index_index.xml change content to following:

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
 <update handle="customer_account"/>
 <referenceContainer name="content">
 <block class="OpsoneKgAdminBlockIndex" name="devis_index_index" template="Opsone_KgAdmin::index.phtml" />
 </referenceContainer>
</page>

so remove layout="1column" and add <update handle="customer_account"/>.

Also as good practice, consider removing your custom block OpsoneKgAdminBlockIndex, and instead move functionalities included inside to View Model like in Magento 2: How to Add a viewModel to a core block? - you can do same with your own when adding block. Then you will have to add view_model as argument to your block and remove class="OpsoneKgAdminBlockIndex" also.

Best regards and good luck :)
