How can I confirm that the only icons I used are available in build output?

[hhimanshu]

Hello,

I am using this project to include some icons, and I got a question

Is there a way I can look at the build output yarn build to confirm that only the icons I used are available in output and not all icons are bundled together?
My project is at https://github.com/hhimanshu/material-icons

The output of yarn build looks like following

➜  build git:(master) ll
total 80
-rw-r--r--  1 hhimanshu  staff   1.0K 14 Jul 06:46 asset-manifest.json
-rw-r--r--  1 hhimanshu  staff   3.8K 14 Jul 06:46 favicon.ico

Could you please help me answer that question?
Thank you
