Query file system?

I recently discovered the file system that is available in the Sisense managed cloud environment. In one of our dashboards, we are linking to folders within that file system where we store documentation that is relevant to the data. Is it possible to query the file system? For example, what if I wanted to know how many files are in each folder in the directory we have set up?

I snooped around the Elasticube settings but wasn't able to identify any endpoints for the file system.
