AWS EventBridge schedule to invoke API Gateway endpoing

I'm trying to build a schedule in AWS EventBridge that is going to invoke an API Gateway endpoint on a specific rate. However, I'm not able to specify the API Gateway endpoint when creating the schedule. I couldn't find examples in the documentation about the JSON body that I need to provide to specify the API Gateway ARN, endpoint and headers.

I reviewed this AWS EventBridge documentation: https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-api-gateway-target.html but did not find details about how to specify the API Gateway endpoint.
