Viewing Airtag mapped locations by owners

How do we see airtag mapped locations? Like the route its been on? For example when an airtag is detected near me, I can see the full route i've been on? Owning the airtags am i able to see that same map for my airtags?

I friend located my AirTag in my car and he was able to see where I have been. Why can’t I see the same map as the owner
