[List Again Please I have updated post] How do you set properties of a component using extension in Dynamic Component extension schema template Updated Examples for MIT App Inventor?

I am creating and testing dynamic component extension schema. I have created an extension to set margin for arrangements. How to define schema for this? Like when we are defining properties of a component we can use extension to pass extra properties that extension has like the block I have shared.

Example

Which dynamic component extension ?

Thanks for reply TIMAI2, this by Ysfchn. Unable to find community post link.

You could just build those blocks in the extension blocks, then export the schema - to get the specific schema?

Did not get this.

Closing, working in Kodular and also asked there.
