Support for GraphQL subscription response giving JSON Patch

[techwizardg]

Do we have samples that illustrate GraphQL subscription to return JSON Patch? We are transitioning towards Server Driven UI and want subscription support with JSON Patch so that every time the user returns to a previously navigated page, we do not want the mobile app to query for the page layout from server via GraphQL and instead should query it first time and then subscribe for changes in pages and these changes to be sent via JSON Patch over subscription response
