How to Integrate App Bridge 4.x into Shopify’s Node.js Boilerplate?

I’m upgrading my Shopify app to use App Bridge 4.x and am working with the official Shopify Node.js boilerplate from this GitHub repository: https://github.com/Shopify/shopify-app-template-node.

I noticed that useAuthenticatedFetch is no longer needed in App Bridge 4.x since authorization is now handled automatically through the global fetch function.

Could someone guide me on the following:

  1. What steps are required to properly integrate App Bridge 4.x into this boilerplate?
  2. Are there any adjustments needed for API calls or other parts of the boilerplate to align with the new App Bridge version?
  3. Has anyone successfully updated this boilerplate to App Bridge 4.x and can share a working example or tips?

Any insights or examples would be greatly appreciated. Thanks in advance!
