Observer mode, How do you use it? xb1

I just tried using it and how do i alternate between characters?? like where is the demographic to show observer mode controls?!?!

I believe bumpers switch between characters. Pretty sure you can view the control scheme in the options menu.

I wish you could spectate hunters in first person in observer mode (not the deadcam). That way you could see how the player is reacting instead of guessing from a 3rd person model.
