Magento 2 – Add custom attribute to custom section admin

I installed my “customsection_adminbackend” module which adds a new menu item in the Magento 2 backend.
For now in this new section there is only a text “Hello world”, but I would like to insert / install some custom attributes in this section of the backend.

What I would like to do is more or less this:

$myCustomSection->addAttribute(
         MagentoCustomSectionAdminBackend::ENTITY, 'descCate1', [
            'type' => 'text',
            'label' => 'Descrizione categoria 1',
            'input' => 'textarea',
            'required' => false,
            'wysiwyg_enabled' => true,
            'sort_order' => 150,
            'global' => MagentoEavModelEntityAttributeScopedAttributeInterface::SCOPE_STORE,
            'group' => 'General Information',
            'is_used_in_grid' => false,
            'is_visible_in_grid' => false,
            'is_filterable_in_grid' => false,
         ]
         ); 

Finally I would like to be able to add the shop filter to my custom section of the backend.
I found this code but I don’t know where to put it:

<filters name="listing_filters">
        <filterSelect name="store_id" provider="${ $.parentName }">
            <settings>
                <options class="MagentoStoreUiComponentListingColumnStoreOptions"/>
                <caption translate="true">All Store Views</caption>
                <label translate="true">Store View</label>
                <dataScope>store_id</dataScope>
            </settings>
        </filterSelect>
    </filters>

The final result I would like to see in my backend custom section is this:

How can I go about installing the two attributes and filter for store view in my custom module?
