CMS Membership and Subaccounts Guidance

I am trying to identify some tools/examples of Webflow sites where a member can add additional users to view/edit content on their private section of the site.

For example: A customer pays for a membership to my site and it allows them access to /customerXcontent. This customer can then allow people from their company to access this content by logging in. No additional membership needed. I could have multiple members with multiple " subaccounts".

I am not sure if this is answered somewhere else on this forum. I could not find it. Let me know if this makes sense?
