Lambda code signing: how to get code signature?

My question is, after signing a lambda function, how can i get the lambda code signature? Because I can't find it.

I created a lambda function using AWS Lambda and signed it using AWS Signer. When deploying the lambda function on my greengrass device i have a file called "aws_signer_signature_v1.0.SF". The content of the file has a leaf certificate. Is it possible that it contains the signature of the code? Or the signature offered by thins certificate is to prove that it has been signed by an Intermediate CA? Because I can't tell.

Here is the aws_signer_signature_v1.0.SF file:
