How to enable the adf-viewer 'view thumbnails' button
I have been trying to enable the view thumbnails button of the adf-viewer component but can't seem to get it to work. I have tried setting the [allowThumbnails] input to "true" but this has not changed anything. Looking at the html in the web tools, I can see that the button has the "disabled" property set in the html of the viewer by default and when I remove it in the web tools the button works as it should. Unfortunately I can't figure out how to accomplish this in my own code. Any help would be appreciated, thanks!
Here is a screenshot of the disbled attribute from the web tools mentioned in the above problem description:
