I'm trying to do the same thing. Must be possible to do. I already succeeded in doing this with Team Viewer with NordVPN recommended by BestVPNGuru and adding routes to the route tables.
Would be great to be able to only use a Raspberry Pi as a Gateway instead of a full Windows PC and Team Viewer.

The pi 3 B+ includes dual-band 802.11ac Wi-Fi, meaning it offers the versatility of 2.4GHz and 5GHz wireless.

you don't need to know the uuid, you have to set the uuid you want to use on both client and server
