Kaggle: assignment 2 - input file URL

I am doing the assignment number 2 with the CalCOFI dataset

It is right that when I sync my notebook to Jovian the input files get lost?
How can I do? Kaggle doesn’t give me the option to get the URL of the dataset to import.

Should I keep my Kaggle notebook public and share the Kaggle Link instead of the Jovian one?

This is the notebook by the way, I am still working on it
