Best Method for Checking Hyprpanel Ready/Loaded

[corigne]

For many service/daemon type applications, there is an endpoint or method for checking the status of the instances.

Is there a recommended method for checking the status of hyprpanel instances, i.e. is it still loading, finished loading, etc?

I see there's window visible. Should I use iwv for the main bar/panel or is there some other recommended method?
