The Approvals app can be accessed from any chat or channel conversation or by using the dedicated app entry point in the left navigation bar in Teams.
With the app open, all you have to do is fill in the details of the approval like the title, description and the users who need to approve it and hit 'Send'. However, you can also add attachments from Microsoft's office software or custom responses to tailor the request to your business needs.
Once submitted, the approvers are notified within Teams and can act on an approval request either from the chat directly using the Approvals card or from within the Personal app. They can also quickly review the details of the approval right within Teams before making a decision to approve or reject it.
Microsoft 365 groups as approvers
After launching in January of last year, Microsoft is now working on a new feature for the Teams Approval App that is slated to roll out next month.
For those unfamiliar, Groups in Microsoft 365 let you choose a set of people that you wish to collaborate with and easily set up a collection of resources for those people to share. These resources may include a shared Outlook inbox, shared calendar or a document library in OneDrive for collaboration on files.
When this new feature becomes available, Teams users will be able to send approval requests to their Microsoft 365 groups which could be useful if approvers aren't using the company's video conferencing software and online collaboration tool.
