Ok guys, hear me out. Act on Both.

The final evolution is the "Acted" pattern: Perform the action on initialization. Then when the user interacts with the button, inform them that the action already occured and there is no need to click the button.

Act on press is great if the action is low risk. Sometimes giving the user an easy out by letting them hold and slide away from a touch button to not execute the action is useful, especially in texting when you notice a mistake

as a react developer I love this "act on both"

No. I am the idiot. What the hells going on here?

Hold to talk is a thing 🤷‍♂️

Act on bug

bro invented "press and hold"

if you didn’t want two actions why did you press and release your mouse button silly user 💻

Windows is very good at Act on None
