The option to make Facebook Messenger chat head shortcuts has been gone since downloading Oreo

[Android Central Question]

I use FB messenger for a lot of my messaging (I know, not the best, but alas), and I use the chat head short cuts from my home screen all the time. I have the original Pixel and since it downloaded Oreo, the option to even create chat heads is gone. I still have the ones that existed before Oreo was downloaded, but I'd really like to add more/update the ones that were there. From some googling, it doesn't appear that FB removed that option, as other people report still having it with Oreo, but I'm not sure how to get it back.
