Ofmeet remote control not working

Hi guys!

I am inspecting openfire for our needs, we need remote desktop control. I installed opefire, Openfire Meetings Chrome Extension, Remote Desktop Control Native Application (I have windows 10), I am able to share screen, also I can share just one single window, but I can not give control to other participants, I don’t have any “allow control” button. Any idea what could be the problem?

I also tries jitsi, they don’t have option to share just one window (but also when I share screen I don’t get anything on the another side)
