Get total one drive for business storage usage for list of users

Good day fellow powershell’ers. I have what I hope is a simple question. How do I get the total one drive for business storage used by a group of users? We can skip the basics…I am connected to O365/Sharepoint online, I am able to get the storage usage for a single user, and I have a CSV list of users I just don’t know how to use the list to get thier total (or list of) one drive for business storage used?

I am not familiar with Office365 cmdlets, but something like this should work.

$users = Get-Content \\path\to\userlist.csv
$results = foreach ($user in $users){
        # Code to get $user storage usage
}
$results | Measure-Object -Property storage-property
