How to turn on Flows?

Long time user of Auth0 - we started 10 years ago and have thousands of users. The UX of this product has become so complex that we’re pretty much defeated by its complexity at this stage.

For example: how do we turn on “Flows”? It looks like something we would like to use and there is absolutely no information on why it’s not available in our navigation under Actions or anywhere else. Trying to log into the flows site just bounces us back to regular Auth0 management.
