I want to compile my lagom project in scala3.
Follow this documentation, when Prepare the dependencies, I change my build.sbt:

lazy val `service-api` = (project in file("service-api"))
  .settings(
    libraryDependencies ++= Seq(
      lagomScaladslApi
    ).map(_.cross(CrossVersion.for3Use2_13))
  )

but lagom api depends other projects can't found.
