Button in lovelace

Hey, do anyone know how i can add a button in Lovelace for a flow that has no physical trigger. I have been using a helper toggle switch for some things but there has to be a better way?

Maybe possible to fire an event from a custom-button-card that node-red listens for. Nothing I have done though. Happy using input_booleans for that.

Here are some suggestions How to trigger a flow in node-red from HA lovelace ui?
