Customising Toast XML to use selectbox items and run custom protocols

Question

Hi,

I have previosly created a script that launches custom toast notification with buttons launching scripts via custom Classes/Protocols. Now i wanted to make it prettier and included a SelectionBox. I am unable to run those custom protocols based on Selected item. Please advise

$ToastTitle = ""  
$Signature = ""  
$BannerImage = 'C:\Users\anowak\OneDrive - Phlexglobal Ltd\Desktop\Personal\Scripts\Toast\lake.jpg'  
$EventTitle = "Testing Title"  
$EventText = "This is where there would normally be info. This is just a test though."  
$site = "http://google.com/"  
$MoreInfoTitle = "More Information"  
$Snooze = $true  
$CustomHello = "Hello $env:USERNAME"  
  
  
#Specify Launcher App ID, the App that will claim ownership of the toast notification, doesn't affect functionality.  
$LauncherID = '{1AC14E77-02E7-4E5D-B744-2EB1AE5198B7}\WindowsPowerShell\v1.0\powershell.exe'
