How can I add ‘Drafts’ menu on profile page?

and show drafts on that tab?

I added this on um-user-posts.php and
$tabs[‘drafts’] = array(
‘name’ => __(‘Drafts’,’ultimatemember’),
‘icon’ => ‘um-faicon-plus’,
);
and
/***
*** @add drafts
***/
function add_drafts() {
global $ultimatemember;
$ultimatemember->shortcodes->load_template(‘profile/drafts.php’);

}
and I added codes for calling drafts So I see ‘Drafts’ tab name but I cant see anything in that tab.
Can you help me?
