Connect a device to tailscale using wireguard credentials

I have a third party device that I don’t have full access to. I am able to create wireguard credentials to connect to it from my machine. Is there any way to add third party wireguard credentials to my tailscale so i can add this device to my tailnet?

I did find this other post discussing a similar issue. I don’t think this solution will work for me.

The wireguard connection i want to add is a docker container. Connecting to it gives me privileged access to other docker containers on that machine.

as far as i know, it is not possible to connect a regular wireguard-client to your tailscale network.
