Angular - Combining validations are not working

Question

I want to combine a set of validations to a bundle, and then re-use it, but it is not working for me, when I apply the validation bundle the control is always invalid.

validation-bundles.ts - Here I define my validation bundles:

import { ValidationErrors, Validators } from "@angular/forms";

export class ValidationBundles {

    static email(): Array<ValidationErrors | null> {
        return [Validators.required, Validators.email];
    }

    static password(): Array<ValidationErrors | null> {
        return [Validators.required, Validators.minLength(6), Validators.maxLength(50)];
    }

}

login.component.ts - Here I use the validation bundles for exmaple:

this.loginForm = new FormGroup({
      email: new FormControl('', ValidationBundles.email),
      password: new FormControl('', ValidationBundles.password)
    });

login.component.html - Here I define the validation error messages:

<mat-error *ngIf="loginForm.controls['password'].hasError('required')">
    Password is required.
</mat-error>
<mat-error *ngIf="loginForm.controls['password'].hasError('minlength')">
    Mininum length is 6 characters.
</mat-error>
<mat-error *ngIf="loginForm.controls['password'].hasError('maxlength')">
    Maximum length is 50 characters.
</mat-error>

So my questions:

1. How do I make this work properly?

2. Can I add more validations to controls when I'm using a bundle? like merging the validations?

3. Are there any best practices related to this topic?
