Using TIdHTTP to click a button on web page

[admctfdotcom]

Hi,

I need to be able to programmatically click a Download CSV button here and save the file locally.

https://www.nasdaq.com/market-activity/stocks/screener

I used TIdHTTP previously for downloading files but not when the button click in involved.
I have to admit i am not much into HTTP GET/POST stuff.

Any help would be greatly appreciated.

Thank you.
