Contact your admin to get approval to install this app

If you are receiving the error below, your Super Admin needs to add the add-on to the Marketplace apps allowed list. They can do so by going to Apps > Marketplace apps > Allow listed Marketplace apps. Select the + icon in the right-hand corner and search the add-on name (Gopher for Chrome, etc). Check the box next to our add-on and select Allow list, then Confirm.
