[Question] How to disable free Highlight Drawing while keeping Text Highlighting?

[lightmagic1]

Hi, I'm using PDF.js and noticed that the highlight annotation feature allows both text selection-based highlighting and free drawing highlighting (where users can manually draw highlights anywhere on the document).

I would like to disable the free drawing highlight while keeping the ability to highlight selected text.

Is there a built-in way to achieve this? If not, what would be the best approach to modify the code to remove only the free drawing functionality?

Any guidance on where to look in the codebase or which configuration options to tweak would be greatly appreciated.

Thanks in advance!
