Alert for Insider Sell

Hi,

I would like to be able to create an alert based on Headlines for a stock.

When I click on the Headlines for a stock I can see news from mtnewswires like this inside TradingView:
www.tradingview.com/...-stoke-therapeutics/

However, I cannot create an alert for an Insider Sell for example.

I want to be able to create an alert in TradingView so that every time an Insider Sell happens for a stock or group of stocks I get an alert.

Thanks.
