Can the admin earn a commission of all fund raising campaigns?

As it's fundraising, the donating person will need their money go directly and fully to the campaign.
Therefore, in workflow perspective, admin shouldn't have any impact on the donation.

The only way admin can monetize from the app is that admin can create a specific User Group which have the option of adding a fundraising campaign and other User Group doesn't have.

This way, admin can sell a subscription, and only users buy this subscription can add fundraising campaign
