Quarkus Datasource issues

Hi,

I am learning Quarkus by following this tutorial. At 19:03 I noticed that I do not get autocomplete for any of the quarkus.datasource properties, but I do get it for the quarkus.hibernate-orm property. The last mentioned is the only one that gets highlighted in orange by IntelliJ, whereas the other four are greyed out.

I decided to ignore this and move on, but when trying to generate persistence mapping like at 20:28 in the video, nothing happens for me when clicking OK in the Import Database Schema window.

I'm running IntelliJ Ultimate 2023.2.5 on Ubuntu 22.04.3LTS, with Docker Desktop. I have followed the tutorial exactly except for the difference that I chose Gradle with Kotlin DSL as build tool when generating the project at quarkus.io. Below is the build.gradle.kts file that was generated.
Thankful for any help!
