How are event viewing rights managed?

The rights to know if we can see certain events come from the "Scope of rights: Others" setting which are applied to know what we have the right to see in the events.

If we have rights on other people, by default when we arrive the first time after logging in on the events page, an automatic filter is set to see only our own events (if we are the intended collaborator, or the one who carried out)

The bell at the top of the page counts down all the events to be processed for us (date limit according to the general options, and filter on yourselves unless we are an administrator)
