License Required error

[bcftv]

I am able to connect to our Corporate account and view users, groups, etc.

But when I try to add a user to a group I get an error that a license is required.

Command:

$api_token = ConvertTo-SecureString -String "REDACTED" -AsPlainText -Force`
Connect-TeamViewerApi -ApiToken $api_token
Add-TeamViewerUserGroupMember -id 123456 -Member @(654321)

Result:

At line:1 char:1
+ Add-TeamViewerUserGroupMember -id 123456 -Member @(654321)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Add-TeamViewerUserGroupMember], RuntimeException
    + FullyQualifiedErrorId : TeamViewerRestError,Add-TeamViewerUserGroupMember

Am I missing something?
