Sunroof leaking down the A-pillar after rain

Water leaks into the cabin down the A-pillar and roof liner because the sunroof drainage tubes are clogged and hard to locate. This leaves owners searching for where the hidden tubes are and how to clear them without obvious access points.

I recently bought a used 2020 Kia Sorento and after the rain we've been getting I discovered that there's a leak in the passenger side of the cabin down the A pillar and behind the passenger sun visor between the roof liner and windshield.source ↗

Where do I find them and how do I clear them? I took the rail and molding off but they're not obviously placedsource ↗

Where is the water coming out if it's clogged? It's not overflowing the reservoir around the sunroof. Water goes down fine otherwise. But can't find where it comes out.source ↗
