Array.Prototype.at Polyfill ?

[franckitho]

Hello !

After reading problem #16651 I saw that PDFJS supports recent browsers (chrome 92+). For the project I'm working on, my application must support browsers from chrome 87 onwards. I tried installing polyfill (https://github.com/babel/babel-polyfills/tree/main/packages/babel-plugin-polyfill-es-shims) but it didn't change anything. Has anyone had the same problem as me?

Here is the configuration:

• Chrome (87-latest)
• PDF.js version: 3.11.174
• Laravel with vue 3 and vite

Thanks !
