Hi,
you would need to replace the featured-image
with page-attributes
.
You cannot just copy that code into a file, you would need to modify it a bit:
wp.domReady( () => {
var removeEditorPanel = wp.data.dispatch('core/edit-post').removeEditorPanel();
// Remove featured image panel from sidebar.
removeEditorPanel( 'page-attributes' );
} );
That should work. Now you need to add it to a JavaScript file that is loaded in the editor, for example, via the enqueue_block_editor_assets
action.
Hope that helps!
