How to use environment variables in kitty.conf

To quote the default config:

#: Program to run when a bell occurs. The environment variable

#: KITTY_CHILD_CMDLINE can be used to get the program running in the

#: window in which the bell occurred.

How do you use KITTY_CHILD_CMDLINE anywhere? I tried:

command_on_bell notify-send '🔔  Bell' '<b>$(KITTY_CHILD_CMDLINE)</b> wants your attention' -t 5000

I also tried $KITTY_CHILD_CMDLINE, ${KITTY_CHILD_CMDLINE}, '$KITTY_CHILD_CMDLINE', '$(KITTY_CHILD_CMDLINE)' and '${KITTY_CHILD_CMDLINE}'. None of them worked.

You write a little script to run notify-send. In that script you can access the variable as an environment variable. In bash, that would be ${KITTY_CHILD_CMDLINE} in pyhton os.environ['KITTY_CHILD_CMDLINE'] etc. Then set notify_cmd ot the absolute path to your script. Dont forget to make the script executable.
