NixOS unable to find binaries/commands/packages installed (globally or locally) by asdf

I recently started to use NixOS 23.05. I'm also using Home Manager (same version). Problem I'm facing is with asdf . I installed it using Home Manager, and everything went fine. I then installed a couple of plugins, but any time I make them available globally, the system is unable to find the corresponding application/installation. I think this may be an issue with NixOS, and the way it *register* the binaries/commands, but I'm not sure how to fix it, because everything was managed by Home Manager. Anyone using this setup?
