PS: To give context, I'm the CTO of Whaly, a Self Service BI like Looker. As a BI is a B2B tool (think Looker) that is deployed to all employees of business and have to match its internal organisations (C-Levels, Data Analysts, Employees) + the fact that many different teams exists (Marketing, Finance, Product, ....), things have to be very customisable by the Customers Admins to adapt the access control to their exact needs and information sharing policy for 100+ users.
