Is it advisable to change/downgrade GNOME shell version from 3.38 to 3.36?

I'm afraid that's something I've been struggling with myself.

I attempted to set it up a while back using Network Displays (available as flatpak, installed by default in ZorinOS Pro) but I couldn't get it to work. Unfortunately I still didn't have the time to try the suggestion by Aravisian as it's not in my home, but maybe some of them may help you.
