2021 CX-9 AC Drain location?

As the title says, I have a 2021 cx-9 and the ac is sloshing around like a kiddie pool. At first, I thought the water on the passenger floor was a spilled drink, but after it persisted, I looked into and realized it must be a clogged AC drain. Looked it up and found some videos on where to locate the drain, but it appears that older models have a completely different underside than what I have.

There is no corner of the heat shield to peel back as seen here:

The only thing I could find online that that looks similar to what I have underneath, is this reddit post with a cx-5:

I brought it to my mechanic and they couldn't find the drain either (even after removing the heat shield). Where on earth is it??
 
Had this problem with another make auto. We had literally pints of water on the front passenger floor. The cause was a spider's web/nest clogging up the drain port for the AC.
