Hi Elton,
Assuming number of items in the side menu list is same as what is provided by default moodle mobile app, you can put below code in your remote css file -
ion-content.has-side-menu-header.mm-sidemenu-menu li:nth-last-child(4) { display: none; }this will hide 4th "li" element from the bottom (which is Help link).
