Loop components, which are currently available in Teams chats, act as smaller applications within a chat that lets you create notes, task lists, numbered lists, and tables on the fly. Adding a loop to a Teams chat allows you to collaborate in real-time right inside the chat – everyone in the chat can edit inline and view changes as they are made.
Ideas for how to use Loop components in Teams include: co-authoring, brainstorming, mini-breakout rooms, and status reports.
Once they are sent in a chat, loop components are automatically saved as fluid files (.fluid) in the Teams chat files as well as in your OneDrive under the Microsoft Teams Chat Files folder.
