function Find-TeamsCallableEntity {
  <#
  .SYNOPSIS
    Finds all Call Queues where a specific User is an Agent
  .DESCRIPTION
    Finding all Call Queues where a User is linked as an Agent, as an OverflowActionTarget or as a TimeoutActionTarget
  .PARAMETER Identity
    Required. Callable Entity Object to be found (Tel URI, User, Group, Resource Account)
  .PARAMETER Scope
    Optional. Limits searches to Call Queues, Auto Attendants or both (All) - Currently Hardcoded to CallQueue until development finishes
  .EXAMPLE
    Find-TeamsCallableEntity "John@domain.com" [-Scope All]
 
    Finds all Call Queues or Auto Attendants in which John is an Agent, OverflowTarget or TimeoutTarget, Menu Option, Operator, etc.
  .EXAMPLE
    Find-TeamsCallableEntity "MyGroup@domain.com" -Scope CallQueue
 
    Finds all Call Queues in which My Group is linked as an Agent Group, OverflowTarget or TimeoutTarget
  .EXAMPLE
    Find-TeamsCallableEntity "tel:+15551234567" -Scope AutoAttendant
 
    Finds all Auto Attendants in which the Tel URI is linked as an Operator, Menu Option, etc.
  .INPUTS
    System.String
  .OUTPUTS
    System.Object
  .NOTES
    Finding linked agents is useful if the Call Queues are in an unusable state.
    This happens if a User is unlicensed, disabled for Enterprise Voice or disabled completely
    while still being targeted as an Agent or for Overflow or Timeout.
