Hello, thank you!
Currently I don't have enough Typescript knowledge to support it right now but all PRs are welcome!

Add this to your env.d.ts:

declare module 'notiwind' {
    import {Plugin} from 'vue'
    const Notifications: Plugin
    export default Notifications
    export function notify(notification: {
        group: string,
        title: string,
        text?: string,
        kind?: 'error' | 'success',
    }, time: number): void
}

The kind property is an extra property used in my custom layout.
Feel free to add more properties if needed.
