Program claims it is streaming on a platform but it it's there - how ot edit

OK https://www.imdb.com/title/tt1898069/ is purported to have S1 on PeacockTV, but it's not available, as of last week, or now. Not sure about the past. I don't see a way of updating the page to inform others of this. Can someone do it for me, and then explain it to me? TIA
