 ## SYNOPSIS
 Get secure raw access token. When using -ResourceUrl, please make sure the value does match current Azure environment. You may refer to the value of `(Get-AzContext).Environment`.
-> **_NOTE:_**  The current default output token type is going to be changed from plain text `String` to `SecureString` for security. Please use `-AsSecureString` to migrate to the secure behaviour before the breaking change takes effects.
