Bug: PDF import via Nimbus Clipper for Chrome does not work

Hello,
when I try to import a PDF file via Nimbus Clipper for Chrome (using actual version 115.0.5790) nothing happens - no preview dialog opens or anything else. The same result I get, if I use the Clipper context menu on the PDF view in Chrome.
