Class NgxGalleryModule is not an Angular module with Angular 12

[Bluejanis]

I have NgxGallerxModule imported like the documentation says:

import {NgxGalleryModule} from 'ngx-gallery';

@NgModule({
  declarations: [
  ],
  entryComponents: [
],
  imports: [
    NgxGalleryModule,
]

Now since Angular Update to 12 it gives the error:
"Class NgxGalleryModule is not an Angular module "

How do I migrate this module to work again?
