Adding a shortcut to a local HTML file in Ubuntu Chrome

I have a local HTML file that I want to run as a Chrome application (that is, it opens in it’s own window and without tabs). For web pages this is done with ‘Create shortcut…’, but it is not available for a local file. In Windows I can achieve this by creating a shortcut to some web page and then editing the shortcut and use the ‘-app’ flag with a path to my local file. How can I do the same in Ubuntu? I tried editing the file I found under ~/.local/share/applications/, but it didn’t work. That is, when I click the icon in the apps grid is still loads the web site in the window.
