Announcements service - No module name

the service-announcement:

is not working after I followed instructions in the README file.

I am getting:

[I 2022-04-25 12:41:07.987 JupyterHub service:132] Spawning /usr/bin/python3 -m announcement --log-level 10
/usr/bin/python3: No module named announcement

Maybe this is related with the fact that I should copy the file to any path location, but this is not explained in the README file, so I do not know what to do with this file.

Any help would be very appreciated.
