Add Contact to AD Group

Hi All,

I am trying to add a AD contact to a Distribution Group through Powershell

I managed to get the AD Object Contact and Group but when I run the Add-ADGroupMember command it returns an error related to the object Contact

I assume that command can't add a contact to a group, it can add only users,  computers and other groups

Seeking your advice, I'd like to avoid editing the attributes through powershell if there is a better way

Thanks
