Win10: Multi-Language Toast Notifications

BEFORE YOU BEGIN
In this blog I will be using a Toast Notification script created by Martin Bengtsson.
TOAST NOTIFICATION 
In my search for a solution to display notifications to our end users during our new Dynamic Driver and BIOS Update process, I found a blog by Martin Bengtsson.
Martin’s Blog: https://bit.ly/35o4sz4​
I will not be deep-diving into the details, so please read Martin’s blog above if you want detailed information about Toast Notifications.
My version is modified to fit our multi-language environment and other needs.
Toast Notification - Danish
Toast Notification - English
Toast Notification - Norwegian
If you can't make it work with "Software Center" as the app for toast notifications, make sure you haven't deleted or hidden the original Software Center shortcut!
Changes I've made: 
Added:
Multi-Language support
Several new text variables in the XML config file
Look in WMI for given name if no local AD is available.
More detailed logging
Changed:
Date formatting
All text can now be edited directly in the XML config file
Log Path
Removed a few script errors showing while running it manually in PowerShell ISE
Deploy it
In my environment we are using ConfigMgr so I want to show how it's done in our environment, but read Martin's documentation to see how it can be deployed through Group Policy.
What I've done in our environment is create a package that contains all the files except the configuration files because I point to them through a UNC path for easier access if I need to change anything.
Explorer - The Files
Then I create a program running PowerShell that executes Show-ToastNotification.ps1, this script will look at the system locale language, and execute the New-ToastNotification.ps1 with the correct language configuration file.
DISM - System Locale Language
ConfigMgr - Program
Command line example:
PowerShell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile -WindowStyle Hidden -File ".\Show-ToastNotification.ps1"
To implement my modified edition of Martin's Toast Notification script to your environment, download it from my GitHub repo.

Script (New-ToastNotification.ps1)
<#
.SYNOPSIS
	Create nice Windows 10 toast notifications for the logged on user in Windows.
​
.DESCRIPTION
	Everything is customizeable through config-toast.xml.
	Config-toast.xml can be locally or set to an UNC path with the -Config parameter.
	This way you can quickly modify the configuration without the need to push new files to the computer running the toast.
	Can be used for improving the numbers in Windows Servicing as well as kindly reminding users of pending reboots.
	All actions are logged to a local log file in C:\Windows\Temp\New-Toastnotificaion.log
​
.PARAMETER Config
	Specify the path for the config.xml. If none is specificed, the script uses the local config.xml
​
.NOTES
	Filename: New-ToastNotification.ps1
	Version: 1.2
	Author: Martin Bengtsson
	Blog: www.imab.dk
	Twitter: @mwbengtsson
​
	Version history:
	1.0 - script created
	1.1 - Separated checks for pending reboot in registry/WMI from OS uptime.
		  More checks for conflicting options in config.xml.
		  The content of the config.xml is now imported with UTF-8 encoding enabling other characters to be used in the text boxes.
	1.2 - Added option for personal greeting using given name retreived from Active Directory. If no AD available, the script will use a placeholder.
		  Added ToastReboot protocol example, enabling the toast to carry out a potential reboot.
​
