Hibernate IntelliJ - Unable to load class [org.postgresql.Driver]

I want to run my own Hibernate application atop of a psql database set up in intellij:

https://jdbc.postgresql.org/documentation/93/load.html does not exactly explain how the xml should be configured...

This is the Error I get:

What am I doing wrong here? I tried renaming the driver to org.postgresql.Driver.jar and moving the jar to the root directory but that didnt help... It might have something to do with the configuration of IntelliJ, but this looks fine to me:
