SalesIQ integration with FB Messenger issue

SalesIQ is not getting the information from the users of the chats from Messenger Facebook, for example the name of the user.
I have to come back to FB Messenger to get the name of the person how's writing us. Is there a confirguration problem from our side, or the integration is not able to get this info from the user?
