An in-game smartphone for VR

Okay so here’s what I want to do:

Currently I have a scene set up in VR and the right hand is cloning the left hand, I want to replace the the right hand with a model of a mobile phone. But i also want that mobile phone to be intractable, nothing major just a device where you receive notifications. The notifications however should pop up out of the screen when you look at it. Any help as to how I should approach this would amazing as I am fairly new to developing in VR.

Thanks.

A 3d widget would be the easiest way to do the display.

Yes, I agree. 3D widget from UMG.
Go find some UMG tutorials for Unreal, that should get you started.
