I cannot recommend the mentioned x11docker cmd line tool enough for this. It takes care of all possible edge cases, supports different outlets (like nxagent or xephyr), focuses on security and exposes an easy interface. I'm using it for day to day work with VSCode, for example, to fix its atrocious security model, or more recently, to try out JPEXS (Java), IDA (wine) and AHK (wine). I specially like that this leaves no config or cache files left behind. The article says you need a compatible image for that, but in my experience, everything launches just fine.
