How can I download files from a Railway persistent volume?

I have a Laravel application running on Railway with a persistent volume mounted at /app/storage.

I need to migrate the application to another server and want to download the contents of /app/storage/app to my local PC.

I can access the Railway container through the Railway CLI/shell and I can see the files, but I don't know how to copy them from the Railway volume to my computer.

What is the recommended way to do this?

Thanks!
