  1. You'll need to install wmctrl
  2. Make sure line #3 points to correct file for you. You can remove this line if you use config in a place that wezterm automatically loads.
  3. DESKTOP_FILE in line #5 is default path when you install using .deb file. In case your installation method is different, change it accordingly.
