Filter out certain internal events in Dashboard?

Hey,

I am testing XWiki to check if it could be used in my business right now. I was wondering that the Dashboard (root path) shows some activity happening in the XWiki space. I am viewing this as a non-Admin user and thought that the following events would be were filtered by the option “Do not show system events” as well: local account creation, XWiki configuration (AuthService.Configuration → OIDC), group synchronization and creation by OIDC. For `AuthService.Configuration` I could deny the view permission. This is not practicable for the whole XWiki space, as it includes things like the user profile.
Can I filter these things out myself or is this a bug?

Also, the pages touched by the OpenID Connect Authenticator extension show up as "Last edited by XWikiGuest”. On the Dashboard this propagates as “Unknown user”. Is it the extension that sets the working user incorrectly? If there is a system user whose activity is reserved to XWiki functionality + extensions, this would explain why these events are not marked as system events. Could this be a bug? Is anyone else experiencing this?
