Chrome-token-signing or web eid on nixos

hello, are there anyone who’s successfully using Estonian web eID on nixos? For some reason browser extension in firefox doesn’t recognize card reader, but the qdigidoc4 app works fine. The issue probably lies into chrome-token-signing package, but I’m not sure how to utilize that with the firefox. Any pointers would be highly appreciated.

Probably I would have to override firefox with wrapper linking chrome-token-signing and firefox together
