You can ref AWS sample code: https://github.com/aws-samples/aws-iot-cqrs-example/blob/master/lib/querycommandcontainers.ts

const getIoTEndpoint = new customResource.AwsCustomResource(this, 'IoTEndpoint', {
            onCreate: {
              service: 'Iot',
              action: 'describeEndpoint',
              physicalResourceId: customResource.PhysicalResourceId.fromResponse('endpointAddress'),
              parameters: {
                "endpointType": "iot:Data-ATS"
              }
            },
            policy: customResource.AwsCustomResourcePolicy.fromSdkCalls({resources: customResource.AwsCustomResourcePolicy.ANY_RESOURCE})
          });

const IOT_ENDPOINT = getIoTEndpoint.getResponseField('endpointAddress')
