How can add an integration with an AWS service for my API Gateway? (instead of Lambda integration)?
```            const api = new sst.Api(this, "Api", {
                  routes: {
                        "POST /": {
                              // @ts-expect-error
                              permissions: [[ev, 'grantPutEventsTo']],
                              handler: "src/lambda.handler",
                        }
                  }
            });```

You have to use <https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-apigatewayv2.CfnIntegration.html|CfnIntegration> and <https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-apigatewayv2.CfnRoute.html|CfnRoute>. Your integration type is `AWS_PROXY` and the Integration subtype is service-subtype. For example:
```integrationType: 'AWS_PROXY',
integrationSubtype: 'StepFunctions-StartSyncExecution',```

<@U01QRRR6TU1> we are waiting for CDK to add high level support for this <https://github.com/aws/aws-cdk/pull/16287>

In the mean while, you’d have to use the low level `Cfn*` constructs to piece together the CloudFormation code as <@U01PENBR2CW> suggested.
