Meshtastic Flasher fails: "python3: command not found" even though I have it

I have Python 3 installed:

$ /usr/local/bin/python3 --version
Python 3.9.1

And yet:

When I find a solution, I’ll post it in this thread for the benefit of visitors from the future.

And yes, it’s in my path:

$ which python3
/usr/local/bin/python3

Opening /Applications/Meshtastic-flasher.app/Contents/document.wflow in my editor and changing python3 to /usr/local/bin/python3 fixed this for me.
