ᐅ Cutout for Downspout in Patio Roof

Hello everyone,
I have the following question: In my patio roof, a cutout in the glass needs to be made for a downpipe (factory-made). Now I would like to ask if there is some kind of trim or cover that I can place around the downpipe to conceal the cutout and, of course, also seal it?

Thank you in advance and have a nice weekend.
Regards,

Could you design it so that the downpipe doesn’t necessarily lead directly into the ground there? (The question might sound strange, but it’s not that unreasonable)

Hello, the downspout is on a house wall. If I plan the roof extension so that I go around it, the roof ends 40 cm (16 inches) earlier than I wanted, and it does not fully cover the house wall. Unfortunately, this no longer looks very good.

Let the downpipe from the house end at the roof of the patio cover and then run off over the roof? This used to be common practice, but it is no longer considered quite appropriate today.
We have the same problem; in our case, the carport installer is having great difficulty making this setup watertight.
