I am trying to use the Zoom Workflow (Beta) initiating via Webhook with a variable type "Zoom User Id" and trying passing an email I receive the answear: "{"status":false,"errorCode":"-1","errorMessage":"illegal member id input"}" It is not possible send the email of the account for Data Type "Zoom user ID"? The email is the best option for a No Code/Low Code model.
