Replacing first 8 to +7

[AeShevch]

Greetings!
I need that if the user enters 8 as the first digit, it is replaced with"+7".
That is, I need not only the first 7 to turn into +7, but the first 8 to turn into +7 as well.
Is it possible to do this?
+7(8##)###-##-## => +7(###)###-##-##

var maskOptions = {
  mask: '+{7}(000)000-00-00'
};
var mask = IMask(element, maskOptions);```

Solution:

const phoneInput = document.querySelector(`.js-phone-input`);
   IMask(phoneInput, {
                        mask: '+{7} (000) 000 0000',
                        prepare: (appended, masked) => {
                          if (appended === '8' && masked.value === '') {
                            return '';
                          }
                          return appended;
                        },
                      });
