How to set up jest to connect an Angular library with an OwlMomentDateTimeModule import?

Question

JavaScript

There is an Angular library with this module:

import { NgModule } from '@angular/core';
import { AngularTestLibComponent } from './angular-test-lib.component';

import { DateTimeAdapter, OWL_DATE_TIME_FORMATS, OWL_DATE_TIME_LOCALE, OwlDateTimeIntl, OwlDateTimeModule } from 'ng-pick-datetime';
import { OwlMomentDateTimeModule } from 'ng-pick-datetime/date-time/adapter/moment-adapter/moment-date-time.module';
import { MomentDateTimeAdapter, OWL_MOMENT_DATE_TIME_ADAPTER_OPTIONS } from 'ng-pick-datetime/date-time/adapter/moment-adapter/moment-date-time-adapter.class';



@NgModule({
  declarations: [
    AngularTestLibComponent
  ],
  imports: [
    OwlMomentDateTimeModule,
  ],
  exports: [
    AngularTestLibComponent
  ],
  providers: [
    { provide: OwlDateTimeIntl },
    { provide: OWL_DATE_TIME_LOCALE, useValue: 'ru' },
    { provide: DateTimeAdapter, useClass: MomentDateTimeAdapter, deps: [OWL_DATE_TIME_LOCALE, OWL_MOMENT_DATE_TIME_ADAPTER_OPTIONS] },
    { provide: OWL_DATE_TIME_FORMATS, useValue: null },
    // {
    //   provide: OWL_MOMENT_DATE_TIME_ADAPTER_OPTIONS,
    //   useValue: MY_MOMENT_DATE_TIME_ADAPTER_OPTIONS,
    // },
  ],
})
export class AngularTestLibModule { }

When I connect this library to an angular application and run tests (in the application), I get an error:

home/ivan/projects/angular-test-2/my-test-app/node_modules/ng-pick-datetime/date-time/adapter/moment-adapter/moment-date-time.module.js:7
import { NgModule } from '@angular/core';
    ^^^^^^

SyntaxError: Cannot use import statement outside a module

The problem is clearly in the imports of modules specified via an absolute path: ng-pick-datetime/date-time/adapter/moment-adapter/moment-date-time.module
How can I solve this problem?
I suppose that this can somehow be configured through Babel and jest, but I just can’t do it.
Below are the application configs.
jest.config.js:

module.exports = {
    preset: 'jest-preset-angular',
    setupFilesAfterEnv: [
        '<rootDir>/jest.setup.ts'
    ],
    transform: {
        '^.+\\.(ts|tsx)?$': 'ts-jest',
        "^.+\\.(js|jsx)$": "babel-jest",
        // "\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": "<rootDir>/__mocks__/file.js",
    }
};

jest.setup.js: babel.config.js:

import 'jest-preset-angular/setup-jest';

module.exports = {
  presets: [
    ['@babel/preset-env', {targets: {node: 'current'}}],
    '@babel/preset-typescript',
  ],
};
