To create an approval from the Approvals hub:
Open the Approvals app in Microsoft Teams.
Select New approval request.
Fill in the name of the request, who needs to approve it, decide approval order, any additional info, and add an attachment if needed.
Select Send. You’ll be able to view the request later by selecting Sent in the hub.
Note: Approvals you create through Power Automate will appear in the hub, too.
