Hi @onkar-rentomojo I am trying to setup Postmessage demo from https://developer.chrome.com/articles/post-message-twa/ but it's failed on onRelationshipValidationResult. Could you please tell me how do you specify

private Uri SOURCE_ORIGIN = Uri.parse("my-app-origin-uri");

Is it just package name eg. https://com.mycompany.myapp ?
