Universal Autofill issues

I'm on a mac and that current auto-fill/type is also useless for me, since i don't always have a window or native fields to put into, but only restricted renderings in a webpage, aka. WebConsoles for VirtualMachines or Citrix Light Client. I have a login-form with username, password and then a field combining the OTP code with a 6 digit static code in front of it (to salt the otp, wtf) to login. I have to do this multiple times a day, also in a browser viewer in a virtual-machine, so no native browser fields, only webgl renderings. I now use a apple-script layed on a shortcut which interacts with 1password cli to get the pw and otp and send those keystrokes in the script.

A solution similar to the keypass feature would also greatly benefit my workflow!
