.SYNOPSIS
Sets the status of the Microsoft Teams client to Home Assistant.
.DESCRIPTION
This script is monitoring the Teams client logfile for certain changes. It
makes use of two sensors that are created in Home Assistant up front.
sensor.teams_status displays that availability status of your Teams client based 
on the icon overlay in the taskbar on Windows. sensor.teams_activity shows if you 
are in a call or not based on the App updates deamon, which is paused as soon as 
you join a call.
