How to allow users to edit each other's posts?

Question

WordPress

There is a custom post type - psvideo (Video). Now users with different roles can create their own entries and see that there are strangers. On the first screen - the page from the administrator role (everything except the entry "42" - his), on the 2nd - the page from the custom role of the manager (his entry - "42"). How to add the possibility of mutual editing of records?
Thank you.

$public_roles = array( 'studio', 'producer' );

foreach ( $public_roles as $the_public_role ) {
    $role = get_role( $the_public_role );

    $role->add_cap( 'read_room' );
    $role->add_cap( 'edit_room' );
    $role->add_cap( 'edit_rooms' );
    $role->add_cap( 'edit_published_rooms' );
    $role->add_cap( 'publish_rooms' );
    $role->add_cap( 'delete_published_rooms' );
}

you need to look at caps, this code will not give such an opportunity, but the essence is
