You can use waypipe.

Wayland was developed by people who got sick of X11. No one who actually dealt with X11 is missing it, most people who complain about wayland and yarn for X11 just miss features that took a while to get right.

Waypipe is quite janky, compared to forwarded X11. On local-only network (host <-> container), Waypipe feels like it's in a different region, whereas forwarded X feels instant, as if the network simply weren't there.
