function Start-DbaPowerBi {
    <#
        .SYNOPSIS
            Allows you to pipe in Get-ChildItem to a PowerBI Template
         
        .DESCRIPTION
            Launches the PowerBi dashboard for dbatools
     
        .PARAMETER Path
            The location of the pbix file. "$script:ModuleRoot\bin\dbatools.pbix" by default.
     
        .PARAMETER Path
            Enables piping but nothing is done with it.
     
        .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.
             
        .EXAMPLE
            Start-DbaPowerBi
         
            Launches PowerBi from "$script:ModuleRoot\bin\dbatools.pbix" using "C:\windows\Temp\dbatools\" (generated by Update-DbaPowerBiDataSource) as the datasource.
 
        .EXAMPLE
            Start-DbaPowerBi -Path \\nas\projects\dbatools.pbix
         
            Launches \\nas\projects\dbatools.pbix using "C:\windows\Temp\dbatools\*.json" as the datasource
     
        .EXAMPLE
            Start-DbaPowerBi -Path \\nas\projects\dbatools.pbix -DataSource "C:\windows\Temp\dbatools.json"
         
            Launches \\nas\projects\dbatools.pbix using "C:\windows\Temp\dbatools.json" as the datasource
