correctly populate fields on trigger of new access agent connecting

I want to set a trigger to tell us when a new Access agent has connected (so we can monitor when new machines are added when we deploy agents using GPO/RMM).

When we do this now, only a couple of properties are actually populated, but the most useful ones like Session.Name, Session.GuestMachineName are blank because (apparently) the trigger is firing before these object properties are fully populated.

Ideally the trigger needs to be delayed until the Session object properties are fully populated.
