Push button in lovelace

Is it simply possible to create a push button in Lovelace to “use” in e.g. node-red?

I am looking for the most simple way without scripting.

(btw. I searched the entire forum but none solutions are complete or satisfying)

You could create an Input Boolean and then add a button which toggles it to lovelace; then let NR react to the state of it and manipulate it as needed.
