I used to trigger the download of sources for maven artifacts using `org.jetbrains.idea.maven.project.MavenProjectsManager#scheduleArtifactsDownloading`. This method is gone in 2023.2. It wasn't scheduled for removal, as far as I can see.
I found `org.jetbrains.idea.maven.project.MavenAsyncProjectsManager#downloadArtifacts` but the class is marked Experimental. Is this still a valid method to download the artifacts? How do I use it? I'm not sure how to use the Continuation parameter or what to do with the returned object.
