Why create a variable here when it's only used once later?

Why do we need to obtain the packageFamilyName if it is already known?

This is not needed... We can hardcode packageFamilyName directly as:

$packageFamilyName = 'Microsoft.Microsoft.DesktopAppInstaller_8wekyb3d8bbwe'

It's constant for this product across all versions so it's safe and faster. This construct is part of the gist which I simply reused as is... It's definitely better not to depend on any APIs, let alone unofficial ones.

$packageFamilyName = ($webpage | ConvertFrom-JSON).packageFamilyName

Invoke-RestMethod will automatically parse the JSON rather than requiring an explicit call to ConvertFrom-JSON
