My Flask App in Glitch doesn't update when I edit the CSS or HTML

I’m making a flask app in Glitch, and when I edit it, it will reload the page with the site i have open, but not include any of the changes. Please help me. What can I do???

Flask caches templates in memory so if you’re editing a templated file, you’ll need to restart the entire app to see changes reflected. On Glitch you can do this by running refresh in the embedded terminal or configuring the watch key in the glitch.json file.
