Need powershell script to add a O365 License

Hello,

I am trying to write a powershell script to add a O365 License to a subset of users.  I figure if I can get it to work for one I can make it work for multiple

This is as far as I get...
Set-MsolUserLicense -UserPrincipalName Mark.jones1@xxx.com -AddLicenses XXX:ENTERPRISEPACK  

I need to be able to add "Microsoft Team" and "Microsoft Planner"  

When I run Get-MsolAccountSku  I dont get the subset of XXX:Enterprisepack

Any thoughts out there?
