Failing to install local-notifications plugin

Ionic Framework Ionic Angular
1

Hi,

   Ionic CLI                     : 6.10.1 (/usr/lib/node_modules/@ionic/cli)
   Ionic Framework               : @ionic/angular 5.2.3
   @angular-devkit/build-angular : 0.901.10
   @angular-devkit/schematics    : 9.1.10
   @angular/cli                  : 9.1.10
   @ionic/angular-toolkit        : 2.2.0

I tried installing ionic-native local-notifications. The installing process does not give any error. I did:

ionic cordova plugin add cordova-plugin-local-notification
npm install @ionic-native/local-notifications

In my app.module:

import {LocalNotifications} from '@ionic-native/local-notifications/ngx'


    providers: [
        LocalNotifications,
        (....here is more.....)
]

On ng serve I get:

    ERROR in src/app/app.module.ts:92:9 - error TS2322: Type 'LocalNotificationsOriginal' is not assignable to type 'Provider'.
      Type 'LocalNotificationsOriginal' is missing the following properties from type 'any[]': length, pop, push, concat, and 26 more.
    
    92         LocalNotifications,

I tried uninstalling local-notifications, deleting folder from nodes_module and installing an older version of local-notifications. But that delivered the same errors.
