Translate reCAPTCHA "Submit" button

Is there no fix within Enfolds code?
I found this topic https://kriesi.at/support/topic/google-recaptcha-how-to-change-submit/ but the code provided there did not work.

I looked through the linked you provided: https://developers.google.com/recaptcha/old/docs/customization
But I cant find any info on how to translate the submit button
It is mentioned how you can change language in reCAPTCHA but its only possible for 8 different languages, and our language, Swedish is not included.

Then there is info of how you can add a custom language. They use Italian as an exampled, but nowhere in that code there is any mention of submit button:

<script type="text/javascript">
        var RecaptchaOptions = {
                custom_translations : {
                        instructions_visual : "Scrivi le due parole:",
                        instructions_audio : "Trascrivi ci\u00f2 che senti:",
                        play_again : "Riascolta la traccia audio",
                        cant_hear_this : "Scarica la traccia in formato MP3",
                        visual_challenge : "Modalit\u00e0 visiva",
                        audio_challenge : "Modalit\u00e0 auditiva",
                        refresh_btn : "Chiedi due nuove parole",
                        help_btn : "Aiuto",
                        incorrect_try_again : "Scorretto. Riprova.",
                },
                lang : 'it', // Unavailable while writing this code (just for audio challenge)
                theme : 'red' // Make sure there is no trailing ',' at the end of the RecaptchaOptions dictionary
        };
</script>
