Correct name from A.J. Donnelly to AJ Donnelly

Hello!A client of mine wants to correct his name with its correct written form. IMDB has him as A.J. Donnelly, but his name has always been credited as AJ Donnelly. I tried pushing this change, but the system doesn't allow me. Any way to do this manually, or any idea on how to do it?https://www.imdb.com/name/nm9176933/CURRENT NAME: A.J. Donnelly CORRECT NAME: AJ Donnelly Thanks in advance! David
