Looks compelling from the app store page! Because I might use it I have to ask - how do permission work around messages? I'd assume something like this:

* Install App

* App cannot passively READ messages

* When I need to use the app, like in a group chat where we are spontaneously planning an event, I can invite it into the chat so that the group can input their preferences

* Other group members (who may also need to install the app) can interact with the widget to submit their planning prefferences

* Widget then WRITES results back to the chat

Does it ever read my messages? Does it ever write messages to the chat? Does my entire group chat need to install it?

Great work. Seems well targeted and that it could help a lot of folks.
