Screensharing Right-click (control-click) on Mac with Chrome does not work

Hi,

I want to use Jitsi to share my screen to students. When I control-click on for instance an album in the Photos-app on my Mac, I see the little menu. But my students do not see that little menu on their screen…

I use:
MacBook Pro - 2019 - 15.10.4
Chrome latest version

Student uses:
iMac - 2019 - 15.10.4
Chrome latest version

Hopefully someone can solve my problem!
