Mapping "option+scroll wheel" to just scroll wheel (Mac)

Hey guys,

Just discovered BTT and super psyched!! on my DAWs (Pro Tools etc) I need to press option and then use the scroll wheel to zoom in and out. How can I map this so that I’m just using the scroll wheel and don’t need to press option at the same time?

I’m using Mac OS Sequoia 15.5 .
I looked around for a while, seems more complex to do this combo than others I’ve seen.

Any help is greatly appreciated
