Electron or Cordova: Because these apps are not served from a domain, you must use the "Unlimited Domains" option or activate the license using the name or productName specified in your package.json.

Salesforce (LWC): In environments like Salesforce, ensure the library is loaded correctly and the key is applied to the global go object before the diagram is initialized. 3. Alternative Solutions (Technical Workarounds)
