Overwrite Custom Labels
If you don't have the option to overwrite Custom Labels, this is likely due to the Translation Workbench being disabled.
Enabling Translation Workbench
- Navigate to Setup → Translation Workbench
- Enable it from there
Once the Translation Workbench is enabled, you will be able to overwrite custom labels. This allows you to customize text and labels throughout the flair application to match your organization's terminology and language preferences.
