Hello dear community of ngx-Facebook.

I'm trying to implement the ngx-favebook libary according to the instruction on:
https://github.com/zyra/ngx-facebook
in my project with Angular 7.3.9, Ionic 4.

First I allready have installed the facebook sdk with the following command line before:
npm i --save ngx-facebook to my Ionic 4 project

Then I have allready added this lines to my app.module.ts
import { FacebookModule } from 'ngx-facebook'; ... imports:[ ... FacebookModule.forRoot() ],

and this to my dashboardtab.page.ts
`
import { FacebookService, InitParams } from 'ngx-facebook';

export class DashboardtabPage{

constructor (private fbService: FacebookService){
let InitParams: InitParams = {
    appId            : 'xxxxxxx',  
    xfbml            : true, 
    version         : 'v3.3'
};
this.fbService.init(InitParams);   

}
}
`
Now when I'll use fb-video tags in the template
I got an issue when I'll start my projekt with the following error message:

ERROR Error: "Uncaught (in promise): Error: Template parse errors:
Can't bind to 'href' since it isn't a known property of 'fb-video'.

1. If 'fb-video' is an Angular component and it has 'href' input, then verify that it is part of this module.
2. If 'fb-video' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("
   <fb-video [ERROR ->]href="{{fbPost.link}}">
   //$(document).ready(function("): ng:///DashboardtabPageModule/DashboardtabPage.html@27:18
   'fb-video' is not a known element:

Can any one help?
