Support for Soledad Theme - Elementor Pro Single post template

Hi all,

I created a single post template using the Elementor Pro Single post template for a specific category using the Soledad theme, however:

I’ve noticed that default **Theme **template doesn’t support elementor as I’m not able to select page template in the Elementor Settings. See screenshot

I want to add the Theme based Elements to the page like “Post Tags, social share and Recent Posts” ( elementor widget not offering grid cards) screenshot attached - Screen Shot 2021-08-23 at 2.15.20 PM

Would anyone be able to guide me in how I would go about adding theme widgets in my custom Elementor based template for design consistency?
