What is the best way to write code to disable copy paste for a textbox in angular 9, Here is my HTML
 

<form [formGroup]="profileForm">
  
  <label>
    First Name:
    <input type="text" formControlName="firstName">
  </label>

  <label>
    Last Name:
    <input type="text" formControlName="lastName">
  </label>

</form>
