{XBOX1} How do you use Flares & Dynamite?

I noticed that the PC version has the option button for use on the screen. On Xbox you don't. So how do you use it if there is no command for it? Or does it prompt you to press something when your at the area you need to be to blow up the wall? I'm confused. Only LvL 70, still new.

You will have to bind them to a button or button combo (they use a skill bind each).

You will have to use the push right stick method (you cannot bind them in the skills menu).

You will have to be in (I think, been a while, you only need to do it once unless you muck around with your bindings) the mine campsite or the Delve itself.

So go to the Delve say, push right stick, a skill bar/menu appears in the lower right. Use it to bind flares and dynamite.

If in doubt, google it - several others have asked at difference places and times in the forums.
