Sliding window?

[Dreinig]

This is going to sound silly but we bought a 2018 Thor four winds 28z. The large windows in the area above the couch have a sliding screen, but I don’t see where windows open???? Only thing I could see is maybe pop out window from outside?? There is a screen for a reason. This is my first RV and I just noticed the screen. I don’t see any way windowS would slide. Anybody familiar with this unit?
Pic attached of windows. Thanks!

Looks like a lock in the middle of center bar of windows

No there is nothing on the metal strip I checked. Nothing on top either. On outside there are 2 what I call coin slots under each window - that’s why I thought maybe pop out.

The two coin slots on the outside are weep hole drains. Look on either end of the window on the inside and look for a horizontal lip - far right or far left. Something that you can get your fingers on. If there is one then see if you can slide the window open. I bet that the center latch on the window is missing..

Well the panel on the right just slides - no handle. I am putting a latch on so can be locked - right now there is none. Explains why we found a piece of wood in the RV when we bought it

Well, there are no handles just a lip where you can catch the window panel with you fingers and slide it. The latch will be the same as the kitchen window or cab over window. I’d take the cab over window latch and put it on the couch window for now. Much harder for some one to climb in the cab over window than the couch window.
