Hi,
Yes, possible to do it. But there have another concern if there not exist first name for a user then what will be there?
Better way, for every user there have settings in user profile here each user can choose how they want their name to be displayed https://prnt.sc/6DImLgHnHOa6
We will plan to inherit few settings in my-account dashboard, so that user can get it easily. Please tell us if you have any other suggestions, how can do it more user friendly.
Thank you
