Microsoft Team App?

Hi, I am introducing to my organization. However, since we currently use Microsoft Teams as our main day-to-day task manager and there is no Spreadsheet app available on Microsoft Teams, it is very tough to convince the executives to consider the changes from PowerPoint, PowerBI, and other apps.

Are there any plans in the future to address this issue?

You can post to MS Teams channels when something is created/changed.

We do not have a MS Teams App - not a roadmap item yet.
