Blynk Client showing button to buy Energy connected to local server

I installed a local Blynk server for my students at school for testing purposes. When I connect with my client to the local server, in the Widget menu appears the option to buy Energy. As I’m using a local server, is there any possibility to not displaying the “+Add” button in this menu?

Best regards,

The add button will obviously be shown all the time but if you want to increase the energy you better visit Blynk Administration site for your Local Server.
