On AWS, I'm using Lambda function which receives event data and custom client context. For local testing, I want to run curl and invoke function with custom client context, defined as:

I dug into codes, and found aws-lambda-rie seems not to add client context to a invoke payload:

So, is there any ways to use custom client context with aws-lambda-rie? Should I send a pull request for this? It seems that Lambda-Runtime-Client-Context header is related to this, but I cannot find a way to use it properly.

Environment: I'm using aws-lambda-rie command in public.ecr.aws/lambda/nodejs:18.2022.12.02.19 image (https://gallery.ecr.aws/lambda/nodejs). Locally, I confirmed my function implementation can receive event data by running curl -XPOST "http://localhost:9000/2015-03-31/functions/function/invocations" -d '{"payload":"hello world!"}', but cannot receive client context by adding Lambda-Runtime-Client-Context header like -H 'Lambda-Runtime-Client-Context: { "foo":"bar" }'. On AWS, my function can receive custom client context.
