Invoking AWS Glue Workflows from Step Functions

Invoking a Glue Workflow from Step Functions got the following error when deploying Cloudformation:

Resource handler returned message: "Invalid State Machine Definition: 'SCHEMA_VALIDATION_FAILED: The resource provided arn:aws:states:::glue:startWorkflowRun is not recognized. 
The value is not a valid resource ARN, or the resource is not available in this region.
at /States/StartGlueWorkflow/Resource' (Service: AWSStepFunctions; Status Code: 400; Error Code: InvalidDefinition;..., HandlerErrorCode: InvalidRequest)

State machine task for starting Glue Workflow.

            "StartGlueWorkflow": {
              "Type": "Task",
              "Resource": "arn:aws:states:::glue:startWorkflowRun",
              "Parameters": {
                "Name": "glue-test"
              },
              "End": true
            },

Glue workflow ("glue-test") exists in the same region, and has a trigger on-demand.

Notes: - Step Functions: Standard - Region: eu-central-1

Can someone shine a light? Is the ARN correct (arn:aws:states:::glue:startWorkflowRun)?

Does Step Functions allow invocation of Glue Workflows? Most examples show Step Functions integration with a Glue Job and not a Glue Workflow.
