        .SYNOPSIS
            Name: Export-UserLicenceBreakdown
            The purpose of this script is is to export licensing details to excel
 
        .DESCRIPTION
            This script will log in to Microsoft 365 and then create a license report by SKU, with each component level status for each user, where 1 or more is assigned. This then conditionally formats the output to colours and autofilter.
