Voice In Log In Window For Changing Desktops

Hello Group,
In Ubuntu24 I have no screenreader in the log in window.
I found a lot of references on line about selecting my desktop from the log in window.
I've changed it in update alternatives but it stays in Mate.
Does anyone know how I can enable the screenreader in the log in window?
I've been able to call it up in years past in the log in dialog, but everything I  try does not bring up Orca.
Thanks for any ideas.
Glenn
