Place it as the response beat right after the line or suggestion it is dismissing in your edit. Pair it by following it with a nope sound for a harder rejection, or precede it with an okay let's go sound when the plan falls apart.

This 1.5-second voice clip has Deimos delivering a flat 'Ehhh whatever' in a bored, drawn-out tone. It gives a listener a dismissive, unbothered feeling, like a verbal shrug that shuts down a silly argument without any real anger. It comes from Madness: Project Nexus, featuring the character Deimos.
