I'm trying to schedule a desktop flow by connecting it to a "scheduled cloud flow" but it requires a machine. It is not allowing me to register the machine I am on for some reason. I have made sure the latest version of power automate desktop is installed. I also confirmed MicrosoftFlowExtensionsCore solution that is greater than or equal to 1.2.4.1. But I do not see the "Machine (preview)" option like the documentation shows. I assume this will allow me to select the machine I am on and then select the Register New Machine option towards the bottom (but I don't see any of that).
This is what I see in my Power Automate Desktop app:

And this is what the documentation shows:

Why can't I see the Machine (preview) option?
Thanks for any help.
