Panoramic Roof Help!

Hello 👋 2021 Toyota Camry XSE here trying to find a solution for this hole on what seems to be weather stripping. I’ve gone to a collision center and the part does not seem to be in the car diagrams and was told to perhaps go to Toyota directly. I wanted to exhaust my options first and see if anyone knows if this is an easy fix, diy-able, or needs professional assistance. Thank you ! (Collision center said I could perhaps fill the hole with silicone wdyt?)
