I'm not sure if my type definition for the CallbackOptions is proper, so just lmk if there's a better way to do them @ap0nia

export interface CallbackOptions {
    onSuccess: (name?: string) => unknown;
    onError: (name?: string) => unknown;
}

I kinda wanna write tests for it, but I don't wanna write tests for it lol.

What do you wanna do Kevin? If you don't wanna test, then I'll just approve and merge 🤓

If it breaks it breaks, and somebody gets extra contribution history 😋

TLDR let's merge 😅, do you need me to do a noop?

[ap0nia]

Yeah I think I need an extra commit from someone aside from me lol. Unless you're able to merge it yourself.
