• $path 

  (string, optional): This parameter allows you to append a path to the network site URL. For example, if you want to link to a specific page or resource on the network's main site, you can provide its relative path here. Defaults to an empty string.
• $scheme 

  (string|null, optional): This parameter specifies the URL scheme to use (e.g., 'http', 'https', 'admin', 'login', 'relative'). If set to null, WordPress will attempt to determine the appropriate scheme based on the current context (e.g., whether SSL is in use). Defaults to null.
