With Approvals in Microsoft Teams, use a template to create a new approval request:
In the Approvals hub, select New approval request.
When the dialog box appears, select Templates and choose the appropriate template.
Add information such as the request's name, recipients, and extra details.
You may not be able to add or remove recipients if a team owner or admin has already selected specific recipients for the template.
Select Send. You'll be able to view the request later by selecting Sent in the hub.
Note: If you're creating a new request in a chat message or a channel, select the Approvals icon and the dialog box will appear for you to select Templates.
