Name: Provide a globally unique name (for example, myappconfig-instance).

Location: Choose a region close to your application.

Click Review + Create , then Create .

The instance will take a few seconds to deploy.

Step 3: Access the App Configuration Instance

Once the deployment is complete, click Go to resource .

You are now in the App Configuration resource.

Step 4: Enable Feature Management

In the left menu, click on Feature Manager (Preview) .

Click + Add to create a new feature flag.

Step 5: Create the Feature Flag
