How can I check the rewrite slug of current post type listing page

Question

Supposed I have these urls: http://my-domain.tld/projects-listing-cpt and http://my-domain.tld/musics-listing-cpt.

The custom post types was setted this way:

Projects:

Text Domain: projets
$args = [
  ...
  'rewrite'            => array( 'slug' => 'projects-listing-cpt' ),
  'capability_type'    => 'project'
]

Musics:

Text Domain: musics
$args = [
  ...
  'rewrite'            => array( 'slug' => 'musics-listing-cpt' ),
  'capability_type'    => 'music'
]

How can I check the rewrite slug of current post type listing page to get something like this:

if( funct_to_get_this_slug('projects-listing-cpt') == 'projects-listing-cpt' ) //show specific things for this custom post type

Looking to the problem from a different perspective, I've reached to a different solution to it.

I've created a function to check the post type instead of checking the slug of the post type. Actually I was trying to assign different CSS Class to each post type

add_action( 'css_class_per_post_type', 'assign_css_class_to_each_post_type' ); // to be called in the place I want the class name to be displayed (I am using timber as the template engine)

function assign_css_class_to_each_post_type( $context ) {

    $post_type = get_post_type($wp_query->post->ID);
    $cssClass = ''; // if no post type, no class is added

    if ($post_type == 'project') {
        $cssClass = 'projects-listing-cpt';
    } 

    if ($post_type == 'music') {
        $cssClass = 'musics-listing-cpt';
    }

    echo $cssClass;

}
