Exporting to local folder:Can't find application file

So I made a small prototype of a game, but I ran into a problem. When I export to local file, I can’t find an application file to run the game. I don’t know if there is supposed to be one or if I’m doing something wrong.

In case you are using GDevelop 5, you exported an HTML5 game. Can use index.html to run the game in Firefox, it won’t run in Chrome unless you have a web server running.

If you need a Windows/Linux executable, with GD5 you can use the online build service, 2 build/day is free. Or you can also use 3rd party tools to package your game like NW.js, Cocoon, Electron.
