How to hide and unhide thumbnail pages on button click?

Which product are you using?
PDF.js Express Viewer

PDF.js Express Version

Detailed description of issue
Hi there,

Do we have a functionality in pdfjs express through which we can hide or unhide the thumbnail page. When we click on an icon beside the thumbnail page , the thumbnail page should have an overlay effect indicating that the page has been hidden and vice versa.

Pls let me know if there is any pre existing way in pdfjs express for achieving this.

Hi Himani,

Unfortunately, there are no thumbnail APIs to create overlays and add that functionality. You will need to follow the steps of this post here: How can we create our custom thumbnail panel beside our viewer? - #3 by Logan
