AWS Chime media capture sdk available for Boto3 python

Question

I want to capture my chime meetings session in a s3 bucket. For this, I'm using the chime-sdk-media-pipelines defined here. When I execute my lambda function I get the following error:

[ERROR] UnknownServiceError: Unknown service: 'chime-sdk-media-pipelines'

It says that chime-sdk-media-pipelines is not a valid service name but I don't know why? I'm using python:3.8-arm64. My docker file:

FROM public.ecr.aws/lambda/python:3.8-arm64
COPY requirements.txt ./

RUN yum update -y && \
    pip install -r requirements.txt
COPY app.py .
CMD ["app.handler"]
