How to trigger Event BeginPlay from level blueprint in sequencer

Hi everyone!
I’ve been working on a film project for over two months and now I’ve gotten to a stage where I need urgent help! I have created an environment in which some of the furniture materials will get dissolved when certain animated objects get close to them. I have scripted the blueprints and it works perfectly fine in game mode but I can’t figure out how to call that in the sequencer. I have read and watch everything online so far but nothing has helped! I would really appreciate if you could help me out. Thank you!
