I'm on a project developing a chatbot, using watson assistant with the node-red platform.  
I would like to know how I can create a button that turns the application on and off. That is, a frontend that when I open the application and click on call, it takes me  
the chatbot page.

Supposedly where the "control panel" is, it would be the frontend but with a button  
bigger (round) on / off and that opens the "main screen" when turned on.  
If anyone can help me, I would appreciate it.
