Typescript errors on Svelte-Kit

[lucagrandicelli]

I'm trying to use this library on svelte-kit but i'm facing some issues with TS. In particular, if a declare my <script> tag in my svelte page as <script lang="ts"> everything works fine but VSCode TS compiler raises up some warnings like the following when hovering on the form element:

"Element does not support attributes because type definitions are missing for this Svelte Component or element cannot be used as such.

Underlying error:
JSX element class does not support attributes because it does not have a '$$prop_def' property.ts(2607)"

which is related mainly to the fact that svelte-up, as a third party library, seems not to have properly type declarations.

Do you have any idea how to overcome this? Thnx.
