False positives occuring with Nextcloud and eBook reader Kavita

sorry for the late answer.
Can’t say for sure, but probably yes.
I’m using subdirectories so whitelist rule is as follows:
- “evt.Parsed.request contains ‘/ombi/api/v’”

But now I switched to subdomains and ombi is now at ombi.example.com.
Is it save to whitelist all my subdomains (ombi, jellyfin, nextcloud, and onlyoffice) or would this brake functionality?
Suggestion: - “evt.Parsed.request contains ‘ombi.example.com’”
I always feel like I should not put too many or too general urls into whitelist…
