1Password from AUR does not integrate with Librewolf

Hey there, for a while I’ve been having issues with the 1Password browser extension, I use Librewolf from package manager (not flatpak or anything) and 1Password Desktop from AUR. Have done https://support.1password.com/additional-browsers/?linux#connect-an-additional-browser-to-1password, but the browser app still cannot connect with the desktop app, meaning I can’t use system auth to log into websites, instead having to input the master password into the extension every time.

$ cat /etc/1password/custom_allowed_browsers 
librewolf

$ stat /etc/1password/custom_allowed_browsers

I’ve contacted support a while back and after some debugging they couldn’t narrow it down, it seems like a Cachy-specific issue. Regular Firefox does integrate fine, just Librewolf is stuck.

I've already tried linking Librewolf's native-messaging-hosts folder to Firefox's, with no luck.
