Pushover and Alarmo, How do I show Alamo variables in Pushover messages?

How do I use Alamo variables such as {{changed_by}} or {{open_sensors}} in a Pushover alert?

I want the Pushover alert for an alarm trigger event to display the sensor that tripped the alarm.

I also want Pushover to state who Armed or Disarmed the alarm. Or use {{arm_mode}} variable in a Pushover message to show the mode activated.

Looks like no one has tried this before or that there is no known way to accomplish this???
