To simplify chat demo translations, a lot of new keys have been added in 0.21.0.989.

If you don't want to change the scene and want to just translate texts / names, you can set json_ChatDemo to 0 & just translate other json_* strings.

If you have already successfuly translated json_ChatDemo, you can keep it as is and don't translate separate strings, but if you don't modify the scene itself, I'd recommend setting json_ChatDemo to 0.
