How to connect a OSC blueprint class to the character class?

Hi! I would like to know how I can connect a OSC blueprint class, which only contains an OSC client, to the character class. Main goal is to send out OSC messages whenever the character is moving. So my guess is, I need to get the OSC BP to communicate with the character class so that onCharacterMovement triggers the OSC clieent to send out the messages. Does that seem right or is there another way? And: how can I connect the Blueprints? Thankful for any advice or idea you can come up with!

I am quite new but I guess you can solve that with Blue Print Interfaces
