I recently build nix-ld to run unmodified binaries. Since the current version of zoom seems to be stuck, I build a working example configuration for nix-ld: nix-ld/zoom.nix at 3d5ca66d585c644b66f15c2844d47de86d49d55e · Mic92/nix-ld · GitHub
You can run it after setting up nix-ld by downloading the repo:
$ nix-shell ./examples/zoom.nix
