I am using pdf.js 4.4.168 to render some pdf in browser, today when I use safari 16.4 to open the site, shows error:

Unexpected Application Error!
Promise.withResolvers is not a function. (In 'Promise.withResolvers()', 'Promise.withResolvers' is undefined)

I am searching from internet that tell me the legacy browser did not support Promise.withResolvers(), we should upgrade the browser to solve this problem. But I still want some old version of user should use the website. Then I tried to use the pdf.js legacy version. What I have tried to download the legacy version, then replace with the legacy one: https://github.com/mozilla/pdf.js/releases/download/v4.4.168/pdfjs-4.4.168-legacy-dist.zip.

After replace the pdf.worker.min.mjs, still did not fixed this issue. This is my legacy js: https://tex.poemhub.top/pdfjs-dist/4.4.168/legacy/pdf.worker.min.mjs. Am I missing something? what should I do to fixed this issue?
