  .SYNOPSIS
    Updates a Menu Object for an existing Auto Attendant
  .DESCRIPTION
    Updates a Menu Object with Prompt and/or MenuOptions or any Menu Settings to update existing Auto Attendants
    This Cmdlet aims to update full Menus only. Updating Menus that Redirect or Disconnect will throw an Error.

  .PARAMETER Menu
    Menu Object. Required. Accepts Pipeline Input of a Menu Object or a Call Flow Object
  .PARAMETER Prompts
    A Prompts Object, String or Full path to AudioFile.
    A Prompts Object will be used as is, otherwise it will be created dependent of the provided String
    A String will be used as Text-to-Voice. A File path ending in .wav, .mp3 or .wma will be used to create a recording.
  .PARAMETER MenuOptions
    MenuOptions objects created with either New-TeamsAutoAttendantMenuOption or New-CsAutoAttenantMenuOption.
    Options that have a DtmfResponse that is present get replaced
    Options that have a DtmfResponse that is not yet part of the menu will be added.
    Please update the Prompt to reflect these new options for the caller
  .PARAMETER RemoveMenuOption
    MenuOption(s) to be removed from the menu. This is processed before the provided Menu Options are parsed
  .PARAMETER Name
    Optional. Sets the Name of the Menu to this value if possible.
  .PARAMETER EnableDialByName
    Boolean. Enables Dial by Name for the Menu.
  .PARAMETER DirectorySearchMethod
    String. Sets the Directory Search Method: None, ByName, ByExtension
  .EXAMPLE
    Update-TeamsAutoAttendantMenu -Menu $Menu -Prompts "Press 1 for Sales..." -MenuOptions $MenuOptions
 
    Updates the Menu Prompt with the provided Text-to-Voice string
  .EXAMPLE
    Update-TeamsAutoAttendantMenu -Menu $Menu -Prompts $Prompts -MenuOptions $MenuOptions
 
    Updates the Menu Prompt with the Prompts-Object and parses each Menu Option provided in the Array $MenuOptions.
    Options that have a DtmfResponse that is present get replaced
    Options that have a DtmfResponse that is not yet part of the menu will be added.
  .INPUTS
    System.Object
  .OUTPUTS
    System.Object
  .NOTES
    This CmdLet does deliberately not offer the same options as New-TeamsAutoAttendantMenu does.
    The use-case for this Cmdlet is to be called by Update-TeamsAutoAttendant CmdLets and to simplify updating of a Menu with Menu Options
    New-TeamsAutoAttendantMenu can be used to create a whole new Menu if it is desired to be replaced.
 
    To define Menu Options manually, please see:
