Javascript: How to specify http method with AWS Lambda.invoke()?

Question

From AWS documentation: https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/Lambda.html#invoke-property

var params = {
   FunctionName: 'STRING_VALUE', /* required */
   ClientContext: 'STRING_VALUE',
   InvocationType: Event | RequestResponse | DryRun,
   LogType: None | Tail,
   Payload: Buffer.from('...') || 'STRING_VALUE',
   Qualifier: 'STRING_VALUE'
};
lambda.invoke(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
});

How do I specify http method, e.g. GET, POST, PUT, DELETE when calling lambda.invoke()?

lambda.invoke() invokes the Lambda function - HTTP methods are for invoking Amazon API Gateway routes, not a Lambda function.

A Lambda function just takes in an event.

Either call the Amazon API Gateway endpoint (which then invokes the Lambda), or just directly invoke the Lambda as above.
