@spec file_path(String.t()) :: String.t()

Accesses notebook file with the given name and returns a local path to read its contents from.

This invocation may take a while, in case the file is downloaded from a URL and is not in the cache.

File operations

You should treat the file as read-only. To avoid unnecessary copies the path may potentially be pointing to the original file, in which case any write operations would be persisted. This behaviour is not always the case, so you should not rely on it either.
