How can I set template for Custom Post Type?

Hello,

i have a custom post type from the directory pro plugin and the cpt lost the astra templates. How can I add the layouts to cpt. In the cpt there is a add review form and if I open the add review form than I don’t have any layout it’s full width layout but I need a boxed layout with right sidebar or boxed layout without sidebar.And the header is transparent but I don’t want transparent header for this cpt.

i inspect the site and see that the cpt don’t have body classes like post-template-default how the blog layout.

I use latest version from WordPress, Astra theme and directories pro plugin.

hope you know what I mean my english is horrible ??

best regards
Hasel
