Caffeine, is it working with remote desktop session?

I' tried to start Caffeine inside a remote desktop session, but it seems that it can stop locking the screen after timeout, I'm missing something? Thank you

It appears that Caffeine will not work in a Remote Desktop Services (RDS) session, per this conversation earlier this year: https://zhornsoftware.forumotion.com/t175-targeted-caffeine-and-remote-desktop-via-rd-web-access

It's worked OK for me in a RDP session - although to be fair I was running it both on the local machine and also on the remote one.
