DataGrip: how to connect to Oracle as SYSDBA

Coming back here two years later, it seems to be not possible anymore to change the advanced properties in the connection settings.

Instead you have to supply sys as sysdba as username. (This might seem obvious but took me a while to find this out)

While there is no easy switch currently, it's still possible to go to Advanced tab in connection's properties and set internal_logon param to sysdba value.
