Custom post type need to show vendor profile

Hi
How can we add one more custom post type to vendor dashabord. I mean from wp-admin profile vendor can see CPT like: drops.

I have tried something like this based on core file. I have added filter in function.php

function add_new_cpt_to_vendor($capabilities) {

        $capabilities = array(
                'drops'   => array(
                'wcv_add_drops'            => __( 'Add drops', 'wc-vendors' ),
                'wcv_edit_drops'           => __( 'Edit drops', 'wc-vendors' ),
                'wcv_edit_drops_published' => __( 'Edit published drops', 'wc-vendors' ),
                'wcv_publish_drops'        => __( 'Publish drops directly without approval', 'wc-vendors' ),
                'wcv_delete_drops'       => __( 'Delete drops', 'wc-vendors' ),
                'wcv_duplicate_drops'      => __( 'Duplicate drops', 'wc-vendors' ),
                'wcv_featured_drops'       => __( 'Featured drops', 'wc-vendors' ),
                'wcv_view_drops'           => __( 'View drops', 'wc-vendors' ),
                'wcv_import_drops'         => __( 'Import drops', 'wc-vendors' ),
                'wcv_export_drops'         => __( 'Export drops', 'wc-vendors' )
            ),
        );

        return $capabilities;

    }

    add_filter('wcv_get_vendor_caps', 'add_new_cpt_to_vendor');

but its not showing under vendor profile in backend. Also have tried with User role editor and i can see all caps are there but still not showing.

Please advice.
