Control composure media capture on/off button in BP

Hello everyone, I am lost and hope to find an answer here.
I have a blackmagic output card feeded from composure.
Everytime, I have to turn on media capture button before I press play in editor.
Is there a way to activate media capture on begin play?
Thank you!

I got it by getting the outputs from composure, taking a copy of the array, choosing index 0 and setting enable to composure pass.
Here is the BP:
