Adding kendo-angular-pdf-export gives 'kendo-angular-pdf-export' is not a known element error message

Question

I know this seems like a duplicate question to this one 'kendo-angular-pdf-export' is not a known element

But I have an angular 14 app where I want to simply add the PDFExportModule into an existing application.

I am currently getting this error:

Error: src/app/pages/reports/meeting-report.component.html:20:1 - error NG8001: 'kendo-pdf-export' is not a known element:
1. If 'kendo-pdf-export' is an Angular component, then verify that it is part of this module.
2. If 'kendo-pdf-export' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.

As a POC, I created a brand new application and followed instructions from here: https://www.telerik.com/kendo-angular-ui/components/pdf-export/get-started/

New Project Ran this code

ng add @progress/kendo-angular-pdf-export

Package was added to package.json

"@progress/kendo-angular-pdf-export": "^12.0.0",

I added the PDFExportModule to the app.modules.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { PDFExportModule } from '@progress/kendo-angular-pdf-export';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    PDFExportModule,
    BrowserAnimationsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

I added this snippet to the app.component.html

<kendo-pdf-export #pdf paperSize="A4" margin="2cm">
  content to be exported
</kendo-pdf-export>

<div class="example-config">
  <button kendoButton (click)="pdf.saveAs('my_document.pdf')">
    Save As PDF...
  </button>
</div>

In the new app, HTML renders and the PDF export works!!

Why might my existing app not be picking up on the export module? And suggestions would be greatly appreciated!
