V0 Webhooks not working, I've tested every possible combination

Has anyone managed to make v0 api platform webhooks work correctly?

I can set them up no problem but they do not fire in any case whatsoever.

I tried both my intended url (https:mywebsite.com/api/webhookendpoint) as well as a webhhook.site url - and subscribed to pretty much all useful events (chat.updated, message.created, message.updated) but recieved nothing at all, anywhere.

I tried both editing a message, sending a new one, updating the chat, both via API and via UI, and webhooks are not firing. Obviously, the same goes for assistant generated content. A message sent by the assistant has also zero effect.

Not that it matters, but I also tried setting chat to unlisted and public, since I tought that having it private might be a problem, but still, this didn’t fix the issue.

Many thanks in advance.
