Where to view progress logs?

It seems that when opening a project, kotlin-language-server spends a long time with high CPU utilization before stabilizing. Presumably, this is an initial indexing operation of some kind. However, it is hard to tell when, or if, that operation will finish.

Where can the user see logs from kotlin-language-server that would indicate its progress on working through a large project, or indeed what type of processing it is doing at all?

Start by tracing how kotlin-language-server handles project opening and initial indexing, focusing on where progress or diagnostic information is currently emitted. Determine whether users can access existing logs and document that path, or identify the relevant processing flow if progress reporting is absent; done means users can tell what processing is occurring and whether it has finished.
