Make an alarm with CloudTime value?

Question

I am trying to make an alarm clock with an Arduino R4 Wifi, so I made a variable connected to iOT which is a CloudTime value. The thing is that I don't understand how to get this value in my code? I tried hour = alarm1.getHour() but it didn't work. I can't find any informations on the internet, so it would help me a lot if someone here knows how to get the value of the CloudTime variable. Thanks!

Here's my full code : (The declaration of the time is right at the end of the code.)

/*
  Sketch generated by the Arduino IoT Cloud Thing "Untitled"

  Arduino IoT Cloud Variables description

  The following variables are automatically generated and updated when changes are made to the Thing

  int day;
  CloudTime alarm1;

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
  which are called when their values are changed from the Dashboard.
  These functions are generated with the Thing and added at the end of this sketch.
