Svelte - Extend standard html elements with typescript

I would like to define my custom component and specify which kind of "standard component" I would to extend.

This to consume VSCode intellisense for all standard attributes of the extended component without re-define all attributes.

This is what I would to do:

<script lang="ts">    // Error: Cannot redeclare block-scoped variable '$$props'    export let $$props: svelte.JSX.HTMLAttributes<HTMLButtonElement>;    // OR    // Error: Cannot redeclare block-scoped variable '$$restProps'    export let $$restProps: svelte.JSX.HTMLAttributes<HTMLButtonElement>;    export let myCustomProp: string;</script><button {...$$restProps}>{myCustomProp}<slot /></button>

To explain better what I would like to do, I post the same case in React with Typescript:

import React from 'react';type Props = {  myCustomProp: string;} & React.ButtonHTMLAttributes<HTMLButtonElement>;export default function ({ myCustomProp, ...rest }: Props) {  return (<button {...rest}>      {myCustomProp}      {rest.children}</button>  );}
