+- Label display names: `{"localeKey":"DisplayName","Settings":[{"Key":"en-us","Value":"English display name"},{"Key":"de-de","Value":"Deutscher Anzeigename"},{"Key":"es-es","Value":"Nombre para mostrar en Español"}]}`
 
-- Label Tooltips: {"localeKey":"Tooltip","Settings":[{"Key":"en-us","Value":"English Tooltip"},{"Key":"de-de","Value":"Deutscher Tooltip"},{"Key":"es-es","Value":"Tooltip Español"}]}
