Get all microsoft teams groups with members and owners

UPDATE 29/03/2020: this article works, but now Teams Module was relaunched and can do quite more things. See my later article: https://blog.it-koehler.com/en/Archive/2074

NOTE: the following actions ONLY shows team groups created in teams, NO converted O365 groups are shown.
For HTML Reports have a look in comments!  

$teamsgroups = (Get-UnifiedGroup | Where-Object {($_.ProvisioningOption -eq "ExchangeProvisioningFlags:481") -or ($_.ProvisioningOption -eq "ExchangeProvisioningFlags:3552") }

$teamsgroups = (Get-UnifiedGroup | Where-Object {($_.ProvisioningOption -eq "ExchangeProvisioningFlags:481") -or ($_.ProvisioningOption -eq "ExchangeProvisioningFlags:3552") } | Select-Object DisplayName,Alias,ProvisioningOption,SharePointSiteUrl,SharePointDocumentsUrl,AccessType,Language,ExchangeGuid,ManagedBy)

This reads all groups with members and also the current manager / owner. We have an overview of the current teams groups within the company.
Criticism and feedback is welcome.
Have fun testing.
