This simple client can be used to demo out:

• float
• fullscreen
• remote
• and potentially split

All of it using gRPC, rather than native wayland clients. agl-shell-activator should be able to something similar to this but for running application, while this examples shows how to do it for the application itself.

I've called alexa-rpc, because I started first with float (which is the popup) like alexa, but if you there's another suitable name I don't mind using something else.
