Not sure if we want just the button (as I added) or we want the full access menu.

Seems to me the access menu has only one valid option in the cloud atm. so adding just the button

ping @dclarizio .

Can we verify what we do for other areas where the cockpit button is shown?
Also, please check the security warning.
Thx, Dan

@dclarizio : The security warning was there before and was actually fixed by @mzazrivec today. Please, ignore it in this PR.
