How to manage multiple AWS Serverless APIs with a single domain?

I created multiple APIs using AWS Serverless Application Model (SAM) and every API created an unique URL with different domain. I would like to manage all APIs under my domain (e.g. https://api.xxx.yyy/function).

Currently I have multiple functions created and I would like to know should I config the subdomain, such that

https://api.xxx.yyy/function1 would be redirected to https://${ServerlessRestApi1}.execute-api.${AWS::Region}.amazonaws.com/Prod, and
https://api.xxx.yyy/function2 would be redirected to https://${ServerlessRestApi2}.execute-api.${AWS::Region}.amazonaws.com/Prod

Thanks in advance

I would aim for this type of setup, where each microservice is a set of functions:

Each API can have its own base path in its serverless.yml file, as in this API of mine, which points to endoints under https://api.authsamples.com/api.

There will then be only one API domain, that maps to the custom domain. My write up explains how I put this together, in case useful.
