Why does aws-sam-cli not support debug mode on os runtime (provided.al2 / provided.al2023)?

Hey,

As the title said, why does aws-sam-cli not support debug mode on os runtime (provided.al2 / provided.al2023)?

Currently I'm trying to use Golang to write lambda functions, and the current aws support for go is linux os runtime (provided.al2023).

And yes, aws-sam-cli does serve the Go lambda function by mocking a api gateway environment (using command like 'start-api').

I was trying to investigate is a way to debug Go lambda with 'Step-Through' break point stuff, and I was imagining is like maybe I could achieve this by using debug mode of sam-cli and delve debugger.

But it seems sam-cli doesn't support debug mode on os runtime. Why sam-cli doesn't have this feature and what is the difficulty?

Btw, does anyone know a way to make the 'step-through' break point debug for Golang at this case?
