For some reason, this information was extremely difficult to find anywhere. Many small and student projects could benefit from working quickly on Unity Collab + Wwise.
So I decided to create a tutorial for others. Hope this helps!
In this video, I cover how to integrate Wwise into a Unity project using Unity Collab as your source control, step by step. EDIT: It's confirmed that you do not need to move your wwise project folder into the Assets/StreamingAssets/Audio folder, but just Assets folder.
