Ion-select modal interface customization

Hi, I am trying to use the modal interface of ion-select ion-select: Select One or Multiple Value Boxes or Placeholders.

I need to replace the CLOSE button provided with a different text and has to be translated with i18n.
Also, I wish to replace the Close button with an icon for the same modal but add aria-label for it. How do I achieve this.

I tried to use the Modal Interface Options to achieve this ion-modal: Ionic Mobile App Custom Modal API Component. But the component passed to it doesn’t help with the close button.

Can you please assist me with this?
