[SOLVED] Where to find the Teammate display name option in `config.json`?

I think I’ve jacked up my config file. Can anyone post the setting in the config file for teammate display since it got put in System Console for v4?

I need to add this setting manually for now, while I figure out why my System Console is not saving settings. It will save when I make changes directly to the config file.

Thanks,
Eric
