Can you add support for YouTube sponsors?

Could you provide me with pointers on their API?
Also, I can only really work on it if I have someone with whom I can test, and I don't know anyone who has the button.

what would you need on your end?
BTW here is a link to the api https://developers.google.com/youtube/v3/live/docs/sponsors

ok, i will try to find someone

The documentation on any API available for the sub button, as well as someone who has the button on their channel and a subscriber willing to cooperate in testing this out. (I can look for documentation myself of course, but if you happen to have it, it would save me time.)

I cannot work on this before the first or second week of february, I've got exams still and I've got some other things lined up requested via email.

I also don't know if it's at all possible, it depends on the API available.
