2023 tacoma Leaking rear power window

So I just got this used tacoma only 20k miles. From the dealer in fayetteville NC and, they said they couldn't find where the leak was and had a specialist come out and he couldn't find it, they sprayed the window apparently and couldn't find it. The tech advisor at rick hendrick toyota of fayetteville said it has a drain and it drains fine, but the water is getting inside the cab and it smells like rotton feet they didnt detail the truck so still smells but, went to pick up the truck I have the truck for maybe 30 min it was raining and found the leak now idk about the drain and Im doubting it's supposed to drain inside the track in the cab but I have some pics from when I first found it also after I picked it up and a video does anyone know about the window drain or have you had issues like this? I've currently got the truck back again at the dealership.
