I added a custom category attribute "Listing Image" and want to display the checkbox "Set Default Value", like "Thumbnail" and "Category Image". I already compared the ui_component, but couldn't find the entry for that.

<?xml version="1.0" ?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">

 <item name="sortOrder" xsi:type="number">10</item>

 </argument>
 <field name="listingimage">

 <item name="uploaderConfig" xsi:type="array">

 </item>

 </item>

 </field>
 </fieldset>
</form>

I already did that as listing grid product, see the image above.

Using:

 MagentoFrameworkViewAssetRepository $assetRepo,

 $this->assetRepo->getUrl('Magento_Catalog::images/product/placeholder/thumbnail.jpg');

1- file Thumbnail.php

 <?php

 namespace PHPAISSJobsUiComponentListingColumnJobs;

 use MagentoFrameworkDataObject;
 use MagentoFrameworkUrlInterface;
 use MagentoFrameworkViewAssetRepository;
 use MagentoFrameworkViewElementUiComponentContextInterface;
 use MagentoFrameworkViewElementUiComponentFactory;
 use MagentoUiComponentListingColumnsColumn;
 use PHPAISSJobsHelperData;

class Thumbnail extends Column
string
 */
protected function getAlt($row)

 $altField = $this->getData('config/altField') ?: self::ALT_FIELD;
 return isset($row[$altField]) ? $row[$altField] : null;

2 - file jobs_job_listing.xml

 <!--
 ** Thumbnail Column
 ** The name 'thumbnail' defined in const NAME = 'thumbnail' in file:
 ** PHPAISSJobsUiComponentListingColumnJobsThumbnail
 -->
 <column name="thumbnail" class="PHPAISSJobsUiComponentListingColumnJobsThumbnail" component="Magento_Ui/js/grid/columns/thumbnail">
 <settings>
 <altField>title</altField>
 <hasPreview>1</hasPreview>
 <label translate="true">Thumbnail</label>
 <sortable>false</sortable>
 </settings>
 </column>
