Minimize applications with PowerShell

I have adjusted the previous 3CX script from 2020 to simply minimize a list of applications. The script will search for matching processes for up to 30 seconds and minimize them. I have this script run on logon. It currently minimizes both 3CX and Voicemeeter Macro Button app.

$processes = @(
    @{
        Name = '3CXDesktopApp'
        Result = $false
    },
    @{
        Name = 'VoicemeeterMacroButtons'
        Result = $false
    }
)

# how long to wait (in seconds) for processes to load before we give up
$wait = 30
