[Noob] VR-360 (Top-Bottom) .H264 Films player on Oculus Go ?

Hi,
We have a 4mn VR360 video (about Net Neutrality) for exhibits, arts installations, etc. and we want to move from Carboard to O.Go
I made the .apk (menu, credits, 2 languages audio) with Unity (my only interrest on it)

I’m very intersted to dive on Unreal for animation and 3D scenes, interactions etc. but not installed yet.

My real question is : Is it easy to make an app for Oculus Go with a menu for 1 VR360 (top-bottom) video and severals soundtracks (in perfect sync) ?

Thanks for your advices.
