Force users to sign using company address
We currently have a department that issues documents to be digitally signed through Adobe Sign. Some signers have Adobe Sign license through their personal email/account.
We would like to restrict their access and sign these documents through their work email address.
According to the below article it seems that it is possible (unless I misunderstood):

My questions are:
- Is it possible? The article wasn't very clear to me.
- If possible, which type of license do I need to have?
- If possible, would we be required to purchase Adobe Sign licenses for all users (who will be signing)?
