Sidelite gets held in place with clips, either and or wall and base. Or channel at the base and caulked at the wall with clips.

Pictures of your planned layout will help.

76" is the planned, glass height, not ceiling height.

I agree and certainly not silicone for this application

Thank you millworkman & Patricia for your feedback! Very much appreciated. Yes on door hinged off of the wall.

I would prefer the fixed panel be mounted in u channel and silicone. Clips hold the glass off the tile surface and are a possible source of leaking as well as being more difficult to clean around. In my opinion, the clips draw attention to themselves instead of allowing the glass to “disappear”.

Mini-clips are the answer. Essentially small short pieces of channel that are perfect in my opinion.

Many thanks everyone!
