Private Messaging

I am having trouble figuring out how to do private messaging. The goal is to click the action button on a post that will pull over the post into the chat. Kind of like when you send or respond to a post on Instagram Dm’s.

So you want to put context into the new message you’re creating, related to the post?

Yes exactly. The post is interactive, so once it is clicked, it is pulled up for the user in greater detail. I have put a floating action button set on that detailed page. I would like to pull the image featured in the detailed page into the chat while creating.
