Hi @Svalinn,
Welcome to the Auth0 Community!
Unfortunately, we don’t have an official sveltekit example or SDK at this time. The closest thing I can suggest would be our nextjs SDK, but that is obviously not the same thing.
I found an unofficial Auth0/SvelteKit Client, but this is totally outside of Auth0 and is not verified by us in any manner. Regardless, it may be worth checking out/contributing to.
