Ubuntu 18.04 tray icon

[thwaller]

I have rclone-browser installed and it is working fine as far as I can see. The issue here is that the system tray icon shows as the default no icon available instead of the proper icon. I can fix this by running from terminal:
XDG_CURRENT_DESKTOP=Unity rclone-browser %U
Is there a way that I can actually fix the issue vs needing to run from terminal?

I am aware of tray icon issues with the removal of Unity, but I have yet to actually find anything that explains how to fix the issue. I tried a few of the install this and that, but none of them worked, so I would prefer to stop trying at random and installing many unneeded packages.
