Problems with TypeScript and Rollup

[JapuDCret]

We are trying to use Chart.js in our project, which uses mostly plain js (with TypeScript).
We downgraded TypeScript to 4.3 to mitigate #9666.

We are using rollup as a bundler and followed the hint here: https://www.chartjs.org/docs/latest/getting-started/integration.html#bundlers-webpack-rollup-etc

But it seems that there are no matching type declarations for these helper functions

error TS2307: Cannot find module 'chart.js/auto' or its corresponding type declarations.

this is basically our code:

import Chart from 'chart.js/auto';

let barchartCanvas = document.getElementById('barchart')! as HTMLCanvasElement;
let ctx = barchartCanvas .getContext('2d')!;
let myChart = new Chart(ctx, {
  type: 'bar',
  data: {
    // ...
  },
});

Are we doing something wrong?
