I don't think there are any instructions available.
We have an outside tv installed in a similar outside space on our unit. It's basically a flat mount that's thin enough to let the mount and tv fit in the space. So you're going to have to do some measuring for depth and find a tv and mount that will fit in there.
The problem is that it doesn't swivel. If I were ambitious, I'd attempt to find a swivel mount, but that's pretty low on my priority list.
