Enable all available themes on custom post type?

I have a WordPress site with the Astra Theme and Elementor plugin.
I have created several custom post types.
I dont know how to get the Template option to show under Summary on the Post settings in Edit mode?

Visibility: Public
Publish: March 15 9:32 am
**Template: Elementor Full Width**
URL: [blahblah.com/hello-world](http://blahblah.com/hello-world)

Basically I want to get access to a Full Width layout for the custom post type(s).

I added in **page-attributes** on this setting:
**’supports’** => array( ‘title’, ‘editor’, ‘thumbnail’, ‘excerpt’, **’page-attributes’**, ‘custom-fields’ ),
but I only get Visibility, Publish and URL – no Template
