Customize the Basic Approval Request

Short answer: No — you cannot customize the “Basic Approval Request” interface in Microsoft Teams Approvals.

The Approvals app in Microsoft Teams is a standard Microsoft interface and several elements are hard-coded, including:

• The title “Approvals”
• The layout of the form
• The fields shown in the request
• The UI branding

So the text “Approvals” at the top cannot be renamed to “Acknowledgement”.

What can be customized

Even though the UI itself cannot be modified, you can customize some fields:

Configurable elements:

• Name of request
• Approvers
• Approval order
• Require responses from all recipients
• Priority
• Additional details
• Attachments

You can structure the request name like:

Acknowledgement – Security Policy Update
Acknowledgement – Compliance Training
Acknowledgement – Device Policy Acceptance

This is commonly used to simulate acknowledgement workflows.

Option 2 – Use Power Automate

If you need more control, create the approval using Power Automate.

With Power Automate you can:

• Define custom approval titles
• Add additional information fields
• Send approvals through Teams or email
• Create acknowledgement-style workflows
• Add automation logic

Example:

Start and wait for an approval
Approval type: Approve/Reject – First to respond
Title: Security Policy Acknowledgement
Assigned to: Users

This still uses the Microsoft approval engine but gives more flexibility.

Option 3 – Full customization

If you need full control of the interface, you would need to build a custom solution using:

• Power Apps
• SharePoint list with Power Automate
• Custom Teams application

In that case the form could be labeled “Acknowledgement”, “Confirmation”, or any other wording you prefer.

Recommendation

For most scenarios, the practical approach is to use Power Automate approvals and define the request title as “Acknowledgement Request”, while using the details section to describe what users are confirming. This provides the closest experience without building a custom application.
