'PlotlyModule' does not appear to be an NgModule class.

We are experiencing an issue when using angular-plotly.js and Angular17 saying that "'PlotlyModule' does not appear to be an NgModule class."

Error

error NG6002: 'PlotlyModule' does not appear to be an NgModule class.

176     PlotlyModule,
        ~~~~~~~~~~~~

  node_modules/angular-plotly.js/lib/plotly.module.d.ts:1:22
    1 export declare class PlotlyModule {
                           ~~~~~~~~~~~~
    This likely means that the library (angular-plotly.js) which declares PlotlyModule is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

app.module.ts

import * as PlotlyJS from 'plotly.js-dist-min';
import { PlotlyModule } from 'angular-plotly.js';
PlotlyModule.plotlyjs = PlotlyJS;

@NgModule({
  declarations: [
    ...,
  ],
  imports: [
    ...,
    PlotlyModule,
    ...,
]
});

Is there something that can be done that will enable this to work?

Start by reproducing the NG6002 error with the Angular 17 and angular-plotly.js 4.0.4 versions listed in the issue. Inspect app.module.ts and node_modules/angular-plotly.js/lib/plotly.module.d.ts, then verify that PlotlyModule can be imported without the Ivy compatibility error.
