I doubt there's an equivalent Teams plugin because the standard solution for that problem in Teams is to click the little telephone icon inside the chat and you're on a call. Add or subtract video and screen sharing as desired. Continue to paste things (documents, links, whatever) inside the call's chat and it's recorded along with the chat/call. I have a lot of complaints about Teams, but there's something to be said for an integrated solution.
