OnComponentBeginOverlap not triggered by player pawn

I migrated the BP_Commentary_Box from Blueprints Feature Sample to my new project.
It used to work fine in a default setup.
But then I created a gamemode with a simple pawn, added controls, but now when I approach the BP_Commentary_Box - OnComponentBeginOverlap does not trigger. How do I make it work?

Some screenshots that I hope would figuring it out:

It’s 4.11.0 project.

check whether the triggerbox has “pawn” on “overlap” inside of the collision settings. same for your pawn he should have the collision type of your trigger box as overlap. the collision type seems to “be physics actor” according to your picture

Yep, that was it! Thanks!
