Angular input binding in structural directive

I cannot find a way to bind multiple inputs in my structural directive:

view

   <div *requiredAccessRight requiredA="[EnumA.A]" requiredB="[EnumB.A]">

directive

   @Directive({
        // tslint:disable-next-line: directive-selector
        selector: '[requiredAccessRight]',
    })
          export class RequiredAccessRightDirective implements OnInit {
                @Input() requiredA: EnumA[];
                @Input() requiredB: EnumB[];
...
           }

during ngOnInit() both Inputs() will end up undefined

The inputs of directive follows naming convention as follows:
> Directive input name = directiveSelector + identifier (first character capital)

So in order to create requiredA and requiredB as inputs you need to have requiredAccessRightRequiredA and requiredAccessRightRequiredB.

After creating these inputs while using the directive, you always need to pass one value as directive name value.

e.g. in requiredAccessRight directive you must have requiredAccessRight as input (this is mandatory).

While using the directive, first value will always be without any iedntifier which will be assigned to directive name value. After that by using ; as separator you can pass other custom inputs.

Directive

import { Directive, TemplateRef, ViewContainerRef, Input } from '@angular/core';

@Directive({
  selector: '[requiredAccessRight]'
})
export class DirectiveDirective {

  private _requiredAccessRight: any;
  private _requiredAccessRightRequiredA: any;
  private _requiredAccessRightRequiredB: any;

  @Input() set requiredAccessRight(value: any[]) {
    this._requiredAccessRight = value;
    console.log(this._requiredAccessRight)
  }

  @Input() set requiredAccessRightRequiredA(enumA) {
    this._requiredAccessRightRequiredA = enumA;
    console.log(this._requiredAccessRightRequiredA);
  }

  @Input() set requiredAccessRightRequiredB(enumB) {
    this._requiredAccessRightRequiredB = enumB;
    console.log(this._requiredAccessRightRequiredB);
  }

  constructor(private templateRef: TemplateRef<any>, private vcr: ViewContainerRef) { }
}

Usage in HTML template

As first value is mandatory you can pass your value from component in place of '' or [], I am just using placeholder here.

<button *requiredAccessRight="'';requiredA: [enumA]; requiredB: [enumB]">click</button>
<!-- or -->
<button *requiredAccessRight="[];requiredA: [enumA]; requiredB: [enumB]">click</button>
<!-- or -->
<button *requiredAccessRight="let i;requiredA: [enumA]; requiredB: [enumB]">click</button>
