Show checkout extension without drag and drop

[abidhasan]

I created checkout extension and using Checkout::Actions::RenderBefore extension point. It works fine when I am developing. But, after installing it on the store it does not render automatically. I have to drag and drop the extension from checkout editor. So, is it not possible or am I missing something?

I believe the app is not added and saved in the checkout editor.

You need to add the app first.

That should work
