Simple Plugin For Unity Send Window Toast Notification with Non-UWP Build Target.
Modify the ps1 to Adapt to your needs.
Not need to put ps1 to Plugins Folder, just find anywhere, and set the path.
Currently the ps1 script takes two arguments, but the implementation uses only one, so you'll need to change that yourself. For Unity, you can follow the Sample implementation by opening PS1 as PowerShell and passing the parameters.
you can only download the ps1 file and use.
