Custom Input for Intent

I'm trying to enable a use case to allow a user to add a Scripting step in Shortcuts that says:


IF <my app's custom state> is <ON>,

do Action.


In Shortcuts, if I select <input>, the options are "Select a Home Accessory", "Clipboard", or "Current Date". I am hoping that list is extensible (it's otherwise comically short), but cannot find how I would extend that as a developer.


Am I missing how to do this or are these three elements truly the only conditionals possible?


Thanks.
