Introduction: Enable Modern Controls in Canvas Studio
By default, they are turned off, you need to explicitly enable them for your Canvas App.

Modern Controls are not enabled by default as they are still in Preview as of the time of writing this post.
Hence, you can see the Classic Insert menu as below.

Open Settings in your Canvas App Studio editor

Now, look for Experimental Features and look in the Preview section (You can also search ‘modern controls’ using the Search in this window to find the option quickly)

Click on as shown in the below screenshot

Now, you can Save the app and do a full-page refresh if required. You’ll now see Modern Controls alongside the Classic ones in your Power Apps Editor.
