**Describe the bug**
I'm following the quickstart tutorial (https://google.github.io/adk-docs/get-started/quickstart/) to test ADK. I'm doing all the project setup on Windows 10. The problem I'm having is that the graphical interface doesn't appear when deploying to the browser. I've tried changing the browser and also trying it in a new tab in incognito or private mode, but it doesn't appear. I read in a GitHub thread (https://github.com/google/adk-web/issues/34) that adding the lines import mimetypes
mimetypes.add_type("text/javascript", ".js", True) to fast_api.py (.venv\Lib\site-packages\google\adk\cli) would solve the problem. However, I'm still having the same problem. I'd appreciate any advice or technical help you could provide.
