Stop character in an endless runner

Hello everyone, I am creating an endless runner for Android devices.
I would stop the race of the character, when I press and hold a button and when I release the button the character starts running again.
how can i do this?

Add a branch between the tick and movement input, then add your input and set the bool value of that branch dependent on if your input is pressed or released.
