Angular 12 Directive causing NG-SELECT disabled feature to malfunction

Looking for a way to disable ng-select using a directive. Does anyone have any suggestions on how to accomplish this?

Here is the code I have been working with, along with an example that I was trying to implement.

setTimeout(() => {
  const selectElement = this.elementRef.nativeElement;
  if (this.elementRef.nativeElement.tagName === 'NG-SELECT') {
    console.log('selectElement :', this.elementRef.nativeElement);
    this.renderer.setProperty(selectElement, 'disabled', true);
    this.renderer.setProperty(selectElement, ' ng-select-disabled', '');
    this.renderer.addClass(selectElement, 'disabled');
    const inputEle = this.elementRef.nativeElement.querySelector('input');
    this.renderer.setProperty(inputEle, 'disabled', true);
  }
}, 1000);

I have tried various methods without success. Ideally, I would like to achieve this using directives. Any insights on how this can be achieved through directives?

[disabled]="true" => works with ngModel
[readonly]="true" => works with formControlName
However, not working with directive.

If anyone has any tips or solutions, please share them!

Check out the StackBlitz demo

To make this work, simply access the host component in the constructor using NgSelectComponent and utilize the setDisabledState method.

import { Directive, ElementRef, Renderer2 } from '@angular/core';
import { NgSelectComponent } from '@ng-select/ng-select';

@Directive({
  selector: '[appCurrencySelect]',
})
export class CurrencySelectDirective {
  constructor(private elementRef: ElementRef, private el: NgSelectComponent) {
    setTimeout(() => {
      const selectElement = this.elementRef.nativeElement;
      if (selectElement.nativeElement.tagName === 'NG-SELECT') {
        this.el.setDisabledState(true);
      }
    }, 1000);
  }

  ngAfterViewInit() {}
}
