ActivityWatch too ambitious for me? (aka I don't understand a word about installing watchers)

Is there anything that we could/ should do as users, in the spirit of contributing to the users’ community; the larger picture, in terms of feedback, or system integration?

E.g. I install apps as “portable” in some instances, and keep a dedicated container for them (regular Win folder, not as in Docker container). E.g. Perhaps some apps aren’t recognized by default – i suspect that’s what is a “watcher”.

I don’t really want to spend a ton of time in configuration, but perhaps there may be a long term benefit to investing some amount of time in it.
Thoughts? Feedback.

Cheers, thank you, and Best regards!
