What is the best way to reuse the connect-wallet modal on 1inch DApp?

I really love UI experience on 1inch dapp: https://app.1inch.io/
Since I have been working on the similar dapp project, I’d like to build a same connect-wallet modal to 1inch dapp.
Is there any open source for this component?
I already searched the team github, but there were too many repositories and could not find the exact one.
