Does anyone have any instructions or guide on how to remove and install rear vent window on a q50?

My driver side rear vent window is crack and I bought a replacement on eBay. Problem is I have no idea how to install it. There are no videos online or guides on fixing this.

Do I need to remove the door panel? Do I need to apply window adhesive? Are there any bolts or screws holding it down? Anything helps.
