FB API Shutting down for Groups? Any ghost native work around?

I have about 1000 people who get a daily video from me via a post and another 3600 people in a FB group that I notify any time I have a new post. Right now I use Zapier to push my posts to this FB group.

From what I am reading, Facebook is shutting down it’s groups API. So Zapier cannot be used to automate pushing posts to FB Groups.

Anyone else use this workflow and have ideas about how to move forward once this API shutdown happens
