How to add disabled attribute to Ion Alert Buttons

How to disable Ion Alert Buttons,
where can we add disabled=“true”.

Thank you.

Add two styles

.alert-button-cancel {

    background-color: blue;
    border-color: blue;
    color:white;
    max-height: 25px;    
}
.alert-button-cancel-disabled{

  pointer-events: none;
  border: 1px solid #999999 !important;
  background-color: #cccccc !important;
  color: #666666 !important;
  max-height: 25px;
}

Set the cssClass based on some condition

 buttons: [ 
        {
          text: 'No',
          cssClass:this.cancelBtnDisabled ? 'alert-button-cancel-disabled' : 'alert-button-cancel',         
        },
        {
          text: 'Yes',          
          cssClass:'alert-button-confirm'
        },    
      ],

I also tried like this only…
but some part of button is not working as disable button.

I mean when I click on disable button to the corner areas. it wont work as disabled button… remaining part of button is works fine… I don’t know why?

Checked by adding handler for the disable button. but handler not executed even on clicking button corner.
