How can I add request header parameters in HTTP integration WebSocket api gateway AWS

After Searching for while I found the Answer from https://repost.aws/knowledge-center/api-gateway-vpc-link-integration

1. To retrieve the integration ID, run the AWS CLI command get-integrations similar to the following:

aws apigatewayv2 get-integrations --api-id <api-id>

2. Create and save a JSON file named integration.json in the following format:

{
    "ApiId": "<api-id>",
    "IntegrationId": "<integration id retrieved from previous step>",
    "RequestParameters": {
        "integration.request.header.ConnectionId": "context.connectionId", //passing context variable connectionId as ConnectionId header to backend
        "integration.request.header.any-header-key": "''static value'",   //passing static value as querystring to backend
        "integration.request.querystring.any-querystring-key": "'static value'"
    } 
} 

3. To update the integration, run the AWS CLI command update-integration similar to the following:

aws apigatewayv2 update-integration --cli-input-json file://integration.json

4. Deploy your API
