In Dokan we have 2 more roles along with the default WordPress roles. Those 2 roles are Vendor and Vendor Staff. Both roles are crucial for Dokan plugin.
A vendor is basically the seller. In another word, the owner of a store. On the other hand, those who works under a vendor, is a Vendor Staff. So naturally vendor has more capabilities than a staff. Although they share some common capabilities too.
