Thank you for this information, the hook work great.

Wouln’d it be a good idea to add a hook for most multi languge extension (at least until Gutenberg natively support it (finger crossed!)). A simple addition to the code could do the trick :

// Set Captcha language
function mosparoOverrideMessages($options)
{
    // Match WPML language if available
    if (has_action('wpml_current_language')) {
        $options['language'] = apply_filters( 'wpml_current_language', NULL );
        
    // Match Polylang language if available
    } elseif(function_exists(pll_current_language)) {
       $options['language'] = pll_current_language(); 
    }
    
    return $options;
}
add_filter('mosparo_integration_filter_frontend_options', 'mosparoOverrideMessages');
