    Name: Get-TeamsStatus.ps1
    Author: Danny de Vries
    Requires: PowerShell v2 or higher
    Version History: https://github.com/EBOOZ/TeamsStatus/commits/main
.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.
.PARAMETER SetStatus
    Run the script with the SetStatus-parameter to set the status of Microsoft Teams
    directly from the commandline.
.EXAMPLE
    .\Get-TeamsStatus.ps1 -SetStatus "Offline"

# Configuring parameter for interactive run
Param($SetStatus)

# Configure the varaibles below that will be used in the script
$HAToken = "<Insert token>" # Example: eyJ0eXAiOiJKV1...
$UserName = "<UserName>" # When not sure, open a command prompt and type: echo %USERNAME%
