how to set up a dotty sdk?

when downloading scala, the max version is 2.13.2

manually registering the sdk doesn't work, intellij doesn't recognize it as a scala sdk.


Any updates on this? I'm using the latest IntelliJ IDEA Community EAP with the latest Scala Plugin Nightly and can't see any option to add Dotty SDK to the existing project (Dotty's project itself).
