Custom App: Pages not loading?

I’m trying to create a custom Desk Page. I created the page and named it ‘test’.

In my custom app, I placed the html file under frappe-bench/apps/my_app/my_app/www/test/index.html.

When I go to urldotcom/app/test, the page loads, but it doesn’t have any of the HTML content.

I tried mIgrate, clear-cache, uninstalling and re-installing the app, and rebooting the server. Still won’t load.

The rest of the functions in the custom app work fine. I can also navigate to the built-in custom pages, for example urldotcom/app/leaderboard loads just fine…
