Shower cabinet - places to NOT use sealant - and detect leak - Please help!

I've a shower cabinet with some leak (water droplets ) to the room downstairs.

I was fairly certain the sealant is at fault - tested by just letting water go in the shower tray - no leak.
But If I spray a certain point where the door closes (seen in pic 2) I get water drops which becomes quicker with more volume.

I've enclosed pics of the outside (pic 1 ) where the sealant seems intact with no water. So I first re-sealed the outside with sealant and used the shower - leak again! Then I put in some sealant at the place where we suspected the leak to be (near the door) but I still get water leaking.

Two questions - Firstly should the place near the door and glass (pic 3) be left with no sealant at all to allow water that has escaped to return back? I was watching a handyman video and he pointed out my amateur mistake. Is it possible that by putting the sealant I've trapped water with no place to go but down?

Secondly - if that area should be left free with no sealant, is it the outside that's surely the culprit ?

Just a bit confused and lost!

Desperate to find the source of the leak!

Any suggestions and advice welcome. Looking for help! :)

Many Thanks

If its leaking through the door where it seals with frame, check if the seal or door position can be adjusted, adding sealant there won’t help.

A loose fitting on the waste underneath the shower tray might also be the culprit.
