By default, the platform does not have this option. You can use the following CSS code to hide the Leave Group button on the Group Directory page. 

Also, Leave Group will only show if you hover your mouse over Organizer on the Group Directory Page. 

Please follow the steps below:

    1. Go to BuddyBoss - Theme Options

    2. Under Custom Codes, enable CSS

    3. Append the following:

button.group-button.leave-group.button.bp-toggle-action-button 

{

    display: none !important;

}

    4. Save changes.

Note: Any modifications are considered as custom work already. Know more about our Support policy here: https://www.buddyboss.com/support-policy/
