How to handle RxJs timeout complete - Angular HttpClient

This works

import { throwError, TimeoutError } from 'rxjs';

catchError((error) => { // Error...
   // Handle 'timeout over' error
   if (error instanceof TimeoutError) {
      return throwError('Timeout Exception');
   }

   // Return other errors
   return throwError(error);
})

I implemented this at my intecerptor that has other functionalities, the code here
