Cloud9 - How to pass an arg used in a dynamodb query to a GET Lambda function using launch.json

Question

Normally I'd pass this info in a SAM local invoke > sam local invoke getAllTracksFunction -e events/event-get-all-tracks.json in an event.  But I want to use the Cloud9 debugger, hence the need to use the launch.json, right?
Here's the launch.json:
        {
            "type": "aws-sam",
            "request": "direct-invoke",
            "name": "API lambda:tracks",
            "invokeTarget": {
                "target": "api",
                "templatePath": "/home/ec2-user/environment/lambda-nodejs16/template.yaml",
                "logicalId": "getTracksFunction"
            },
            "api": {
                "path": "/tracks",
                "httpMethod": "get"
            },
            "lambda": {
                "runtime": "nodejs16.x",
            }
        }
I haven't found this question ever being asked here, so I'm assuming that it's obvious, but not to me. A link to the documentation on this would be great!
Thanks for any help.

Hi,

These pages have additional information about configuring ```launch.json``` :
1. https://docs.aws.amazon.com/cloud9/latest/user-guide/sam-debug-config-ref.html
2. https://docs.aws.amazon.com/cloud9/latest/user-guide/serverless-apps-toolkit.html#sam-run-debug

In the *lambda* configuration properties, you can configure the ```payload``` option to reference your ```events/event-get-all-tracks.json``` file

Excerpt from [Configuration options for debugging serverless applications](https://docs.aws.amazon.com/cloud9/latest/user-guide/sam-debug-config-ref.html)

**payload**  Provides two options for the event payload that you provide to your Lambda function as input.  
    ```"json"```: JSON-formatted key-value pairs that define the event payload.  
    ```"path"```: A path to the file that's used as the event payload.
