function Get-DbaXESession {
    <#
    .SYNOPSIS
        Gets a list of Extended Events Sessions from the specified SQL Server instance(s).
 
    .DESCRIPTION
        Retrieves a list of Extended Events Sessions present on the specified SQL Server instance(s).
 
    .PARAMETER SqlInstance
        The target SQL Server instance or instances. You must have sysadmin access and server version must be SQL Server version 2008 or higher.
 
    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
    .PARAMETER Session
        Only return specific sessions. Options for this parameter are auto-populated from the server.
 
    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
