error TS2339: Property 'X' does not exist on type '{}'.

Describe the bug

I run npm run build then got this error

src/renderer/src/App.tsx:11:15 - error TS2339: Property 'X' does not exist on type '{}'.

11   window.api?.X();
                 ~~~

// App.tsx
function exampleOnly() {
  window.api?.X();
}

Which I know the error is from:

// package.json
    "build": "npm run typecheck && electron-vite build",

which then resolve to:

// package.json
    "typecheck": "npm run typecheck:node && npm run typecheck:web",

which is

// package.json
    "typecheck:web": "tsc --noEmit -p tsconfig.web.json --composite false",

npm run typecheck:web

src/renderer/src/App.tsx:11:15 - error TS2339: Property 'X' does not exist on type '{}'.

11   window.api?.X();
                 ~~~

// *.d.ts
import { ElectronAPI } from '@electron-toolkit/preload'

declare global {
  interface Window {
    electron: ElectronAPI
    api: {
      X: () => void
    }
  }
}

All right, thank you! It works after I modified the preload/index.d.ts. But, I think it would be nice if it could be done automatically.
