@snehankekre I hope this looks good.

PS: I couldn't find which npm version was required for the build, on 8.19.2, it gave me a possibly critical warning as:

npm WARN deprecated [email protected]: core-js-pure@<3.23.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Some versions have web compatibility issues. Please, upgrade your dependencies to the actual version of core-js-pure

I thought I should mention it but since I'm fairly new to npm I'm not sure if it really is troublesome or not.

The callout looks good to me. Thank you for your contribution, @achieveordie!!

Thanks for pointing out the issue in npm versions. I'll create a follow up PR to clarify the build instruction in our README.

Personally, I've been using npm 8.11.0 by following the installation steps in the Streamlit library repo. I'll post those instructions to this repo.
