I imported a code component following the tutorial https://youtu.be/xqUBFJfNvyM Later on, I don't need it anymore, so I deleted it from the app. Here is the screenshot to show that there is no more code component:

However, the issue is that this code component becomes the dependency of the app even I had deleted it from the app. Please see the screenshot below. I got this screenshot from the Solution, and show the dependency of the app.

Does anyone know how I can remove this dependency?
Thanks!
