Microsoft will add another interesting functionality to Teams. Co-authoring content in Teams will be much easier. You will be able to send a chat message containing a live component that can be edited inline – in real time – by everyone in the chat.
The roll-out is planned for mid-end of August.

Fluid components in Teams chat will allow you to send a message with a table, action items, or a list that can be co-authored and edited by everyone in line and in the future will be shareable across Office applications like Outlook. Colleagues will be able to quickly align across teams, and get work done efficiently by copy and pasting components across Teams chats.
With Fluid components colleagues can ideate, create, and decide together, while holding fewer meetings and minimizing the need for long chat threads.
