How to deactivate Error log on Chat?

Good Day Everyone.
In the Chat section “Everyone”, it not only involves all the users, but it also involves the Error log and Activity log.

Is there a way to make the posts in Chat only used by the users, or a way to deactivate the posting of Error log and Activity log on Chat??
The Main Point is, to have a Page to make Announcements to the users, and for discussions among each other.

Thank You :slight_smile:
