Any way to change XWiki username display format to use the "fullname" attribute instead of [first_name, last_name]?

Hello everyone,

I have encountered a problem while using XWiki and I hope to get some help.

Currently, the username display format in XWiki is fixed as [first_name, last_name], but most of my Wiki users are from East Asia, where people are used to displaying names as [last_name, first_name].

Therefore, I have extended a user profile attribute called “fullname” by XWiki Class Editor, but the username display still uses the original format, and “fullname” attribute won’t be displayed anywhere.

Is there any way to change the username display format to use the fullname attribute? Thank you!
