How to display time on end play?

I’m trying to create a BP that on end play pops up a message with the time taken to complete the map and possibly a score of how many gates (trigger volumes) on the map the player has used.

What’s the best way of doing this and is there anything similar out there that I can refer to for its construction?

How about adding DeltaSeconds to a variable on each EventTick? On EndPlay you can then read that variable to know how much time it took.

Any chance of a step by step?
