    final normalized = candidateString.substring(2);  // Remove "a="
    GlobalLogger().i('Stripped \'a=\' prefix from candidate string');
    return normalized;
  } else if (!candidateString.startsWith('candidate:')) {
    // If it doesn't start with "candidate:", add it
    final normalized = 'candidate:$candidateString';
    GlobalLogger().i('Added \'candidate:\' prefix to candidate string');
    return normalized;
  } else {
    return candidateString;
