Hi guys, i just received my gopro setup as shown in the pic..

Im wondering how should i attach my setup to my body to prevent losing my setup?
What im thinking of is just attaching a lanyard from the tray to my BCD.
However do u guys think i should also attach the gopro also? or attaching the tray is enough?
I actually came across this youtube video, however im kind of worried that like while being underwater if i tug it too tightly the back housing might pop out or something.
cheers guys!
