On the candidates job Offer Notification, customize the error message linked to the Accept button

Summary:

During job offer process , we seek additional info from the candidate through a generated mail, where they have to enter the some additional details asked for.

if the details are provided then candidate will be able to “accept” the offer.

If the required additional info is not provided by the candidate and they try to 'Accept' the offer this error message is shown (check is done using a fast formula). Need guidance to change this standard error message displayed to a customized one.
