Creating a Authorizer for API:GatewayV2 (HTTP api) with a custom lambda authorizer using CFT

I have created HTTPapi and have integrated with the application load balancer, all this is working using CFT.

Now I wanted to add the authorizer to the API endpoint, I am able to implement it through console. But I am not able to figure out by CFT.

Documentation of Authorizer: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigatewayv2-authorizer.html CFT for reference, currently I am receiving error as "Invalid Authorizer URI: I have given the arn of lambda function.
