Thanks!
That is what I was looking for.

PS: The issue was that fcc unlock wasn't enabled by default.
https://modemmanager.org/docs/modemmanager/fcc-unlock/

Sadly, that information isn't being shown to the user nor logged by
default in journald.
I think such messages should belong to the error log instead of the
debug log.
