Getting arguments for register_post_type from a plugin generated post type

So I was wondering if there was anyway to get arguments for use in register_post_type for the post type that is generated by the plugin so that don’t have to use the plugin?

You can use get_post_type_object( string $post_type ). See Documentation and example usage here.

$obj = get_post_type_object( 'certification' );

print_r( $obj ); 

Above code might return something like this, so you can get the arguments used by register_post_type ():

stdClass Object
(
    [labels] => stdClass Object
        (
            [name] => Certification
            [singular_name] => Certification
            [add_new] => Add New
            [add_new_item] => Add New Certification
            [edit_item] => Edit Certification

        )

            [edit_published_posts] => edit_published_posts
            [create_posts] => edit_posts
        )
)

I hope this may helps.
