         .SYNOPSIS
         Keep you "green" in Teams, while the process is in the background

         .DESCRIPTION
         Keep you "green" in Teams, while the process is in the background

         .PARAMETER LoopTime
         Time, in seconds, to wait between the loops.

         The default is 120 (e.g., 2 minutes)

         Minimum is 30 seconds (Do not brute force Teams!)
         Maximum is 300 seconds (Should prevent status flickering)

         .EXAMPLE
         PS C:\> Invoke-KeepYouGreenInTheNewMicrosoftTeams

         Keep you "green" in Teams, while the process is in the background

         .NOTES
         "Did not call you, because you where away in Teams!"
         And I was active, but Microsoft Teams was minimized (Background) and I did my job: Write Code in my favorite editor.

         So, I came up with this Idea!

         What doe it so?
         It activates the minimized Microsoft Teams app, send some dummy key strokes and make a inactive again.
         You current window should not even realize that we did that!

         And as a benefit, it should keepalive your session, like "awake" (PowerToys) or "Caffeine"!

         Please do not abuse this in any kind...
