This post shloud not be lost: Modern security: We need Wireguard.
So basically I am looking how to add WireGuard to Network Manager for normal people like customer care employee etc.
I think that this move would be really nice for Gnome.
Probably there is missing only GUI for this feature: https://blogs.gnome.org/thaller/2019/03/15/wireguard-in-networkmanager/
