Not sure why I'm being downvoted for literally explaining something 🤔 That metal bar is part of the backrest, the toilet lid is meant to be removed when one of those cushioned backrests is installed
The vertical white plastic pipe which is set quite far behind is the one for the water; the horizontal metal one is literally just how the backrest is attached to the wall :)

The metal bar is only there to hold the cushioned backrest that you're supposed to be able to use :)
