Angular Apply validators only on specific field of object

I have a reactive form with a form array in it. When I init my form, I push some form controls with default values in my form array.

Here’s the code:

formValues?.tipsAndTricks?.forEach((tipAndTrick) => {
  this.tipsAndTricks.push(
    this.fb.control(
      { id: tipAndTrick.id, tip: tipAndTrick.tip },
      { validators: [Validators.required, Validators.minLength(25), Validators.maxLength(2000)], updateOn: 'change' }
    )
  )
})

The problem is that my validators are not working because they are applied on an object: { id: tipAndTrick.id, tip: tipAndTrick.tip }.

My question is how can I apply these validators only on the tip field of this object ?
