a button where you can click on and then you switch to a temporary guest session, like ubuntu has

I wish the feature that there is a button in the panel or in the mint menu where I can click on and then switch into a temporary guest session. This feautere is included in ubuntu since many releases.
The command to switch to the guest session is only "/usr/share/gdm/guest-session/guest-session-launch". I think it is not so difficult to implement this feauture and I think that many users are missing this very useful feature. It is not difficult to make this on your own, but its not comfortable.

thanks for thinking about it.
