Sharing Externally using Control Center


I'm new to using control center and I have an internal team that wants to use it to create client specific reports and dashboards in addition to our internal information. The problem is there is certain information on the sheets that I don't want the external client to have access to, so I can't share a report with them. I would love to utilize Dynamic View, but I can't use this in Control Center. I can't do a published report, because that also won't work in SCC (right?!)

The only solution I can think of is to encourage them to purchase a WorkApp user package and share information that way. Are there any options I'm not thinking of?
