function removeTextPatternWithLineBreaks() {
  const doc = DocumentApp.getActiveDocument();
  const body = doc.getBody();
  const paragraphs = body.getParagraphs();

  paragraphs.forEach(paragraph => {
    const text = paragraph.getText();

    // Adjust pattern to handle line breaks (Shift+Enter in Docs)
    const pattern = /javascript\s+copy code/gi;

    // Check if the pattern exists in the paragraph
    if (pattern.test(text)) {
      // Replace the matched pattern with an empty string
      const updatedText = text.replace(pattern, '');
      paragraph.setText(updatedText);
    }
  });
