We already covered that in your thread entitled "What should I put
inside the file called wlan0?" You must remember, as it created
a brief back-and-forth:

https://lists.debian.org/debian-user/2022/03/msg00026.html

Any time you forget again, you can check for yourself,
as the file is created (when necessary) by the script:
/var/lib/dpkg/info/ifupdown.postinst (q.v.).

Cheers,
