Joint credit card addition during a mortgage application

Dear experts,
I have recently accepted for a ftb mortgatge and currently waiting for home valuation to get accepted by the lender prior to morgatge completion. My credit history is good and only 1 cc under my name.
Unfortunately, today my wife add my name into her credit card during a call with the cc company. She does not posses good credit history, therefore I have only applied for the mortgage against my name.

Q1. Is this credit card inclusion will gonna affect my credit history and is it going to adversely affect my mortgage application??

Thanks a lot for your time and support. Regds,
