It’s been a long while since I used it and at one point I did figure out how to browse it, but I remember documentation pointing out that it’s meant to be left alone and do all your file management through NextCloud itself.

Sometimes I needed to do big file operations or drop in a chunk of data straight from the server, but it wouldn’t ingest those files unless I did a sync or upload them using the client.

Maybe things have changed, but last I used it, it was 14 services that were all sort of good when I needed the service to do one thing really well.
