Testing VR without putting on headset

Is it possible to test a VR experience on my monitor with just mouse and keyboard? I don’t want to have to put on the headset and teleport to the right place in the VR Preview each time I make a small change. What I’m looking for really is the ‘Eject’ experience, only with game interaction with trigger boxes etc.

I’ve looked at many questions around this topic but I’m not fully understanding the answers because of my noobosity - am I correct in thinking the best workaround is to add a Character and then possess the character, using a hotkey?

I use the “simulate” option for that.
