Are you referring to the top 3 performing tableau "posts"? i.e. the workbook/sheets with the highest number of views?
If so you should be able to get this from your Postgres repository.
Regarding your "load it via a hyperlink URL", are you referring to a dashboard URL action? i.e load the view from another dashboard?
I want it to load automatically. So list the top 3 categories and load the pages directly via hyperlink URL
