Connecting OSC to Cubase

Hi there,
I do apologise if I’ve missed a glaringly obvious part of the process - but could somebody point me to the direction of connecting OSC to Cubase? I have created a Generic Remote in Cubase, but I’m unsure how to connect the two and assign my buttons correctly.

I’m on Mac - I can’t install RTMidi or LoopMidi

Any help would be appreciated.

Thanks in advance!
