title: How to configure gtm to track OrderPlacedEvent in SAP-Spartacus?
body: <p>I am using Spartacus 4.2 and i am tracking a bunch of events via GTM.
  I have configured gtm to track some custom and standard events but when i try to add the OrderPlacedEvent i get the following error:</p>
  <pre><code>Type 'TmsConfig' has no properties in common with type 'Config'
  </code></pre>
  <p>The import for OrderPlacedEvent looks like this:</p>
  <pre><code>import { OrderPlacedEvent } from '@spartacus/checkout/root';
  </code></pre>
  <p>GTM-Configuration:</p>
  <pre><code>    provideConfig({
          tagManager: {
              gtm: {
                  dynamicConfiguration: true,
                  // TODO: Add events for tracking here
                  events: [
                      NavigationEvent,
                      OrderPlacedEvent,
                      //... (custom Events)
                  ],
                  debug: true,
              },
          },
      } as TmsConfig),
  </code></pre>
  <p>Does anybody know what im doing wrong?</p>
