How do I use Enterprise Features?

I am super confused by the enterprise features.
I want to be able to run this via Java client on a local instance as well as AuraDB

"CREATE OR REPLACE DATABASE neo4j;"

What do I need to do?
Do I have to provide a licence to the driver? or maybe to the server?
If you could also point me to the documentation for how to set up the enterprise edition it would be great.

Hello, the server you are using is either from the Community Edition (CE) or the Enterprise Edition (EE), there is nothing to do really.
If you try e.g. to run "CREATE OR REPLACE DATABASE " against a CE server, you'll get an error back.

OK great so it's on a server side.
Is AuraDB by default an Enterprise server? It says "Professional" next to the instance name. But I only know about Community and Enterprise. (I tested the query and it fails so Aura is actually a community edition?)
sorry for being so confused but I don't have direct access to the AuraDB website. only to the connection URL.

In that particular case, it appears that AuraDB does not yet support multi-tenancy, so you cannot create databases like you're trying to do here. Other features (such as specific EE indices & constraints are available however).
