Jitsi with custom UI

I am trying to find information around using Jitsi features with a custom UI, We are working on building a complete new UI in react and invoke the jitsi features behind the scenes. While reading the forums i understood that there are libraries associated to each features. Can someone tell me how these libraries / api/ functions can be leveraged with custom UI, What are the prerequisites and how do i go about invoking the underlying api for these features. Any help on this is greatly appreciated. Thanks for the help

Can you be more specific about what is it that you want to customize? You can get the latest code from the repository, edit it, make it and host it just like that.
