Using Wwise for DemoReel

Question

Hello,

I want to do a sound design\audio-implementation demoreel video using simple self-made games created just to show my skills with Wwise.

These are the questions,

Can i use the Wwise-trial mode to implement audio on a private self-made game which won't be published?

or do i have to register the project to get the appropriate license?

does the trial mode allow me to integrate sounds into unreal engine and unity engine?

Thanks,

RP
