I have read the previous issue https://github.com/charmbracelet/gum/issues/75 which makes sens, but this is a single command and even providing the PID of the background process does not work

[rm-dr]

This isn't a bug in gum, or in any other application. As such, this issue should probably be closed.

Even though sleep 10m & gum spin -- wait is one command, that wait will not work. wait can only wait for child processes, and sleep is not a child process of gum.

You could do a few things:

• Make a script that contains your code
• Use tail --pid=$pid -f /dev/null instead of wait (linux only), as in gum spin -- tail --pid=18889 -f /dev/null (source)

Pardon the hand-wavy explanation, I need do to some reading on child processes. In fact, you might want to do that too!

If it simply requires I child process, that makes perfectly sense!
