Hi @JosephAnson, I have defined a collection for markdown files and want to use csv files also.

Following the csv instructions here however, doesn't seem to work for me as nuxt is expecting me to define a collection before I can use query collection to fetch the csv.

There is however no example that points out how to do this.
