The chat bubble lets you contact customer support without leaving Sarbacane. If it gets in your way, you can hide it from your profile and show it again whenever you like. This setting only applies to you.
Be logged in to your Sarbacane account.
In the top-right corner of the screen, click your avatar.
In the left-hand menu, click Profile, then open the Preferences tab.
Turn the Chat support toggle on or off.
The chat bubble appears or disappears immediately in the bottom-right corner of the screen.
Accept the site's cookies, then reload the page: the bubble will not appear while cookies are rejected.
