Describe the bug I can't Exec config to launch anything..

I have create a custom image from kasmweb/core-ubuntu-focal:1.15.0.. but I can't get anything to launch with exec config:

{
  "first_launch": {
    "cmd": "/usr/bin/bash -c '/usr/bin/xterm'"
  },
  "go": {
    "cmd": "/usr/bin/bash -c '/usr/bin/xterm'"
  },
  "assign": {
    "cmd": "/usr/bin/bash -c '/usr/bin/xterm'"
}

I have also tried with just "xterm"... but nothing spawns.. just the background (menubar is disabled)

If I run the docker exec command on the command line, the program spawns fine...
