Multiple CPT for Oceanwp Metabox

Hi,

How do I get the Oceanwp Settings Metabox for 3 of my CPT?

I tried this but manage to include one only. How do I add in the other 2?
The slugs are
1. uni-college
2. programme
3. landing-page

/**
* Add the OceanWP Settings metabox in your CPT
*/
function oceanwp_metabox( $types ) {

// Your custom post type
$types[] = ‘your-post-type’;

// Return
return $types;

}
add_filter( ‘ocean_main_metaboxes_post_types’, ‘oceanwp_metabox’, 20 );
