Compatible with Google and Outlook calendar.
The flow sets ringer mode to vibrate during appointment and changes back to ringing when it ends.
Just make sure your status on the appointment is set to "busy", but that should be the default setting.
Only appointments flagged with busy status are recognized. All other are ignored and ringer mode is not touched.
So in case you don't want the ringer to be changed, e.g. on a several days appointment like a journey, just set your status to free.
Click on Calendar URI in the first block (await Event) and select your desired calendar.
