So, interested on this workaround, right?
I am using 'Filter array' to get event is in the future and discard the ones in the past:

You can leave 'Get my profile' input empty
Now for the 'Apply to each' input I am selecting 'Filter array' body output

Finally, these are the values for 'send an HTTP request...' URI input:
https://graph.microsoft.com/v1.0/users/@{outputs('Get_my_profile_(V2)')?['body/mail']}/events/@{items('Apply_to_each')?['id']}/attendees
Hope this helps
