[Publish API] How do I update the original BackendApi? My other Publish APIs will also update. Just update the Image again. Other configuration parameters remain the same?

I am using the platform to develop and create quite a few ChatBot. Use them for many purposes and mount on many different platforms.
The difficulty is that when I modify the source code features, I have to delete the Publish API and recreate it, or update the Lambda Image for them (Sometimes it doesn't work).
Does anyone know any workflow to automate them?

No file, test, or entry point is identified in the issue. First map how Publish APIs and Lambda images are created in this repository, then define an automated update workflow that preserves the other configuration parameters and verify it across multiple published APIs.
