By the way, has anyone tried Waterproof Case?
On Aliexpress there are cheap ones with a rounded head, something tells me that it will not be visible in this case or will not focus.
And in General, as a native, there are similar ones with a transparent cap but the shape of the head is the same as the original one.

Fits waterproof case from Pocket 1 to Pocket 2?

it comes in hard and it comes out even harder
