Show comments based on user role in front end

Question

I want to allow commenting on a custom post type by a specific user role. And a user can see only his comments only.

Scenario is

e.g User roles are student and instructor. The Student can comment on a lesson, which is a custom post type. An instructor can see his comment and then reply on it. Same the same student John can see only his comments and replies on his comments by his instructor.

I used the link for reference also using the comment_form for reference.

Please check this

$args = array('post_author' => get_current_user_id(),);
$comments = get_comments( $args );
$list_args = array(
   'reverse_top_level' => false 
);
wp_list_comments( $list_args, $comments );
