How to use a file's link as data source in QuickSight.?

I am using a dataset from GitHub which gets updated on a daily basis.
How to use this file as my data source.?

There is no way to do this directly with the github datasource connection.

You would need to do some ETL pipeline that dumps this data into a source that quicksight can extract from.

Example: add a step that dumps the file to s3 when it get’s updated. Then connect to the s3 file in quicksight and refresh it everyday.
