Enabling environment visualization
Allow the Docker container to access the X server on your machine by running:

xhost +local:docker
and while running the Docker container, add the following arguments to docker run:

-v /tmp/.X11-unix:/tmp/.X11-unix
-e DISPLAY=$DISPLAY
-e QT_X11_NO_MITSHM=1
For example:

docker run
-it
--rm
-e MJKEY="\((cat ~/.mujoco/mjkey.txt)" \ -v /tmp/.X11-unix:/tmp/.X11-unix \ -e DISPLAY=\)DISPLAY
-e QT_X11_NO_MITSHM=1
