      .EXAMPLE
      Disconnect-Rubrik -Confirm:$false
      This will close the current session and invalidate the current session token without prompting for confirmation
 
      .EXAMPLE
      $rubrikConnection = $RubrikConnections[1]
      Disconnect-Rubrik
      This will close the second session and invalidate the second session token
      Note: The $rubrikConnections variable holds session details on all established sessions
            The $rubrikConnection variable holds the current, active session
            If you wish to change sessions, simply update the value of $rubrikConnection to another session held within $rubrikConnections
