boto3 apigateway get_method doesn't return a "body". Similar cli call does.

I create a boto3 session and client for my aws apigateway like this:

self.b3_session = boto3.Session(profile_name="aaa", region_name = 'us-east-1')
self.api_gateway_client = self.b3_session.client('apigateway', region_name='us-east-1')

I then make a get_method call to my api gateway:

        response = self.api_gateway_client.get_method(
            restApiId='abcdefg123',
            resourceId='123ab',
            httpMethod='GET'
        )

This is what I get back:

{
    "apiKeyRequired": "False",
    "httpMethod": "GET",
    "methodIntegration": {
        "integrationResponses": {
            "200": {
                "statusCode": "200"
            }
        },
        "contentHandling": "CONVERT_TO_TEXT",
        "timeoutInMillis": 29000,
        "uri": "arn:aws:apigateway:us-east-1:lambda:path/.../invocations",
        "httpMethod": "POST",
        "passthroughBehavior": "WHEN_NO_MATCH",
        "cacheNamespace": "abcdef",
        "type": "AWS_PROXY",
        "cacheKeyParameters": []
    },
    "methodResponses": {
        "200": {
            "responseModels": {
                "application/json": "Empty"
            },
            "statusCode": "200"
        }
    },
    "ResponseMetadata": {
        "RetryAttempts": 0,
        "HTTPStatusCode": 200,
        "RequestId": "xxxxxxxx-xxxx-xxx-xxxx-xxxxxxxxxxxx",
        "HTTPHeaders": {
            "x-amzn-requestid": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
            "content-length": "611",
            "x-amz-apigw-id": "xxxxxxxxxxxxxxxxx",
            "connection": "keep-alive",
            "date": "Wed, 06 Nov 2019 22:45:47 GMT",
            "content-type": "application/json"
        }
    },
    "authorizationType": "NONE"
}

I'm expecting a 'body' element with a list of names.
I'm able to get the intended response using the aws cli:

aws apigateway test-invoke-method --rest-api-id abcdefg123 --resource-id 123ab --http-method GET --path-with-query-string '/myfunction' --profile aaa --region us-east-1

What am I doing wrong? I couldn't find documentation for passing in the "path-with-query-string" parameter '/myfunction'. Is that the problem?

Is this is low level response and I need to follow a process to get my list of names? Thank you.
