Unable to upload csv to Metabase in the Metabase v0.47.0

I have installed the Metabase v0.47.0 version on my local machine. I'm not able to configure the CSV upload. Can someone share any resources on how to set it up?

Docs are here: Uploading data

Main things to remember:
Postgres/SQL only for the uploads
Need to have enabled the option
Schema security needs to be correct
