AEM Remote SPA Modelmanager is rendering content in localhost but after building with react-scripts content was not rendering in UI.

I'm Working on Remote spa,

I followed the documentation of remote spa which is wknd-app.

I have a react app running locally with modelmanager.initialize() and content was rendering properly in localhost. Which means I'm able to see the text and title in UI.

After build, when i run serve -s build locally content was not rendering by modelmanager. Here, not able to see the text and title in UI.
