Want to open a HTML file in text editor, not only in browser

Let me assume I have a HTML file in a Katalon project, namely “terrible.html”. In the Tests Explorer I can find the file.

When I select the file and double click it, Katalon Studio forces me to see it in browser; it does not allow me to open it in a Text editor. Therefore I have to start some Editor software (Emac for me) and open the HTML in there.

I want an option in KS to open the HTML either in Text editor or in browser.
