hola @magestein ... The code for the playground (and actually for all the website) is already available in Github. you can find it here.
The code for the controller Workflow Playground is here. As it is not dedicated to be shared, the code may not be really clean ... 😎
Hola @raoul2000 , es posible que puedas subir el ejemplo de Playground al repositorio? serviría mucho tener de ejemplo directo
Eng: Hi @raoul2000 , is it possible that you can upload the Playground example to the repository? it will help to have a direct example
