I want to translate the red words.
You can make your own KarmaBank language file by following the docs here: https://docs.vanillaforums.com/developer/locales/#overriding-locales-with-the-subcommunities-plugin-or-the-multilingual-plugin
For this page all localizable strings are located under the /KarmaBank/views/karmabank.php file
(Search for T('KarmaBank.Transaction','Transaction') and simillar)
And for the Reactions title, it's from the YAGA application, not KarmaBank.
