How can I create a truly transparent TextBox (no white fill)?

[rk250ky]

I’m new to docx.js and need to insert a floating TextBox in my document header that has no fill and no visible border just the text itself. Every approach I’ve tried still produces a white background or outlines around the box.

Is there a built-in way in docx.js to make a Textbox completely transparent and remove its borders? Any guidance or simple examples would be really helpful. Thanks!
I am using 9.3.0 version.

maybe not best solution but fixed it by fetching and patching object xml. Replaced parts that needed change with this logic:

` const patchedXml = documentXml.replace(/<v:shape([^>]*?)>/g, (match, existingAttrs) => {
let attrs = existingAttrs;

  if (!/filled="f"/.test(attrs)) attrs += ' filled="f"';
  if (!/stroked="f"/.test(attrs)) attrs += ' stroked="f"';

  if (/style="([^"]*)"/.test(attrs)) {
    attrs = attrs.replace(/style="([^"]*)"/, (m, styleContent) => {
      let updatedStyle = styleContent;
      if (!/mso-wrap-style:/.test(updatedStyle)) updatedStyle += ';mso-wrap-style:behind';
      return `style="${updatedStyle}"`;
    });
  } else {
    attrs += ' style="position:absolute;z-index:-251658240;mso-wrap-style:none"';
  }

  return `<v:shape${attrs}>`;
});`
