[apigatewayv1] Manual HTTP Method Creation Required for Resource Integration Setup

api gateway v1 - https://github.com/aws-controllers-k8s/apigateway-controller

Issue with Creating Integration for Resource in AWS API Gateway V1

There is a limitation when attempting to create an Integration for a Resource. The current process requires the HTTP method to be manually established for the Resource using command line tools or Terraform before an Integration can be created. This step cannot be bypassed or automated within the current workflow, causing an additional manual step in the integration process.

Impact:

This constraint complicates the process of setting up integrations, as it necessitates manual intervention to define the HTTP method on the Resource before proceeding. This manual step can hinder automation efforts, making it more challenging to streamline deployment and integration workflows, particularly in environments that rely heavily on Infrastructure as Code (IaC) and automated pipelines.

Steps to reproduce
Apply the following yaml file in the cluster

apiVersion: apigateway.services.k8s.aws/v1alpha1
kind: RestAPI
metadata:
  name: example-restapi-name
spec:
  name: example-restapi-name
  description: "api-gateway-description"
  endpointConfiguration: 
    types:
      - PRIVATE
---
apiVersion: apigateway.services.k8s.aws/v1alpha1
kind: Resource
metadata:
  name: example-resource-name
spec:
  restAPIID: dev-hcp.export-root-resource-id
  restAPIRef:
    from:
      name: example-restapi-name
  parentID: example-the-parentid-of-restapi
---
apiVersion: apigateway.services.k8s.aws/v1alpha1
kind: Integration
metadata:
  name: integration-name
spec:
  resourceRef: 
    from: 
      name: example-resource-name
  restAPIRef: 
    from: 
      name: example-restapi-name
  httpMethod: POST
  integrationHTTPMethod: POST
  type: AWS_PROXY
  uri: example-uri-to-aws-resource

Expected outcome
Integration should create the http method by automatically by itself, or the ACK should have another kind that creates the http request.

Actual Result
The following error displayed in the .status.conditions:
"NotFoundException: Invalid Method identifier specified"

status:
  ackResourceMetadata:
    ownerAccountID: "00000000000"
    region: eu-central-1
