Meeting Connector is not avaiable for new Sub Account

Hello,

I recently created a new sub account for a subsidiary company of ours. We got already other sub account. On this new sub account I cant find the Tab "Meeting Connector". This Setting is missing. On the other Sub Accounts is it avaible. What can I do, that my Sub Account has access to our ON-Premise-System?

Pleas help.

Thank You so much
