List audit events that are not filterable even for filtered/whitelisted users

On this page https://docs.couchbase.com/server/6.0/manage/manage-security/manage-auditing.html#filterable-events, where we instruct how a user can whitelist some users to prevent audit logging related to these filtered users. However, it might be useful to add to the docs what (or better, what not) is a "filterable event". For example, I believe an attempt to login with bad credentials on a whitelisted/filtered user, will still trigger an audit log, so such event is not filterable. I think it would be worth adding a list of those exceptions.
