Hi,
I previously attempted to reseal my shower with silicone after some obvious signs of water leak. However, it appears that water is still leaking as seen from the video below.
After doing some investigation, it appears that the water is coming in and exiting from this gap between the glass shower screen and metal frame. When I put some tap over this gap to "temporary seal it" when doing some testing, the water leak stopped. Am I meant to seal this gap? or am i missing something else.

Also, this was the signs of water leak/damage that the previous owners did not addressed. Which I am trying to resolve by first resealing the shower.

Any suggestions or insights would be greatly appreciated.
