Correct way to update with Docker Compose?

[2600box]

Hello, is there a special way to update monica with docker compose?

Normally I use WatchTower to do this automatically. However for monica I get the following error:

If I try manually with `docker compose pull` I get the following error:

~/monica$ docker compose pull
[+] Running 1/2
⠿ app Warning 1.5s
⠿ db Pulled 1.3s
WARNING: Some service image(s) must be built from source by running:
docker compose build app
1 error occurred:
* Error response from daemon: pull access denied for monica-app, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

I can do `docker compose build app` but I am not sure if that is the correct way to update and it would be great if I could make it work with WatchTower?

Thanks!
