Best glass epoxy/adhesive for glass for the back window

My passenger side back window that vents isn’t sticking to the mount. What’s the best glass epoxy to use to re stick it? The motor still works perfectly just need something to get it to stick. I’m currently trying Permatex 5 minute epoxy and have a few more hours to go before it’s fully cured maybe it works but if not I’d like to see what others have used to fix this.
