Set `dandiset_id` to be the ID of the dandiset you want, and set `dandi_filepath` to be the path of the file within the dandiset. The filepath can be found if you press on the `i` icon of a file and copy the `path` field that shows up in the resulting JSON. If you are accessing embargoed data, you will need to set `dandi_api_key` to your DANDI API key."
