Dead Heat - collect all the endings

After completing the event, it only added the victory cutscene for the team I actually supported most, to my library. I was able to see the other endings on youtube, but I’m curious how any one person was able to gather all of them. Shouldn’t it be one per account? Or is there a way to see the other endings in-game?

After the event ends everything that you missed gets added to the Materials/Event quest log/ section in My Room so you can watch them there anytime.
I did the event already last year so I can see them now but it should update the same way for you, well maybe without Jeanne.
