What is the correct way to use clipboard service destroy?

[ShivamShokeen]

@ViewChild('container')container:ElementRef;

copyText(){
    this._clipboardService.copy(this.container.nativeElement.innerText);
  }
  clear(){
   this._clipboardService.destroy(this.container.nativeElement.innerText)
  }

I want to clear the copied text for that I am using destroy but it was giving an error of

container.removeChild is not a function

Can you tell me how to use destroy function. I can also use below code but this is not what I want

this._clipboardService.copy(' ');

Thank you :)

Because it is not designed for you to use it. this._clipboardService.copy(' '); I think it is what you can do. If you have more question, please ask in Stackoverflow.
