How to get anchors in bookmarks?

[ChinaChenMingQuan]

I haven't looked at the source code, I'm making suggestions as a user.

Configuration:

Web browser and its version: Google Chrome 121.0.6167.86
Operating system and its version: Windows10 x64
PDF.js version: 4.0.379
Is a browser extension: No, it's Github Page.

I need to read the anchors in pdf bookmarks. If you don't understand, I'll put it another way, I need the specified number of pages in OutlineNode.
