Magic Mouse 2: how to emulate logitech middle wheel and click and hold (orbit mode in various cad programs)

I am pretty new to BTT and I am trying to find my way around the app. I am trying to simulate the logitech middle button equivalent (click and hold) with a MM2. I need it to orbit around my 3d object under BlackMagic Fusion 9 (also under 3d cad progams like autocad fusion 360). Does anybody how to go about it?
