Shared api package across platforms?

We have React and React Native applications at my workplace. Tell me if I am wrong, but in order to use Universal Login, one must implement Auth0 using the SDKs? This is rather coupled to the platforms. Does the Auth0 API allow a business to create their own Auth package to share across their platforms (mobile, web)? Can the Auth0 API do everything that the SDKs do like integrate Google / Apple Sign-in?

If anyone has any large organization implementation experience, I would appreciate any guidance on how to share reusable auth code across our org.

Thanks!

Hey there @emiller !

Basically our engineering teams are working with one core principle in mind if something is doable with our stack using our API it should be also doable in our SDKs and using most parts of our Management Dashboard UI.
