Question: Jest + Typescript + threads.js how can it work together ?

I have implemented threads.js in my "vue + typescript + electron" project and it works, but my test now fails with the error:

```
pinguSync\src\backend\controller\main-list-manager\worker\main-list-search-id-worker.ts:1
import { expose } from 'threads/worker';
^^^^^^

SyntaxError: Cannot use import statement outside a moduleJest
```
"worker.ts":
```
import { expose } from 'threads/worker';
import Series from '../../objects/series';

const worker = function findSeriesById(buffer: Series[], id: string): Series | null {
return buffer.find(x => x.id === id) ?? null;
};

export type MainListSearchIdWorker = typeof worker;

expose(worker);
```
"main":
```
public static async findSeriesById(id: string): Promise {
const worker = await spawn(new Worker('./worker/main-list-search-id-worker.ts'));
return worker(MainListManager.getMainList(), id);
}
```

"test":
```
describe('test fn: findSeriesById', () => {
test('should find Series by Id', async () => {
const series = new Series();
MainListManager['mainList'].push(series);
const result = await MainListSearcher.findSeriesById(series.id);
expect(result?.id).toBe(series.id);
});

test('should return on no result', async () => {
const result = await MainListSearcher.findSeriesById('id');
expect(result).toBeNull();
});
});
```
(You can turn Series to a object with just a id for reproducing):
`{id:''}
`

JestConfig:
```
'use strict';
