Place it near the end of a short reaction edit, just after the moment of agreement is shown on screen. Open with Oh My God Wow for the surprise, then let this clip confirm it, and close with Damn Meme Sound Button for a final beat.

This short clip centres on one drawn-out, satisfied yeah, delivered in a calm male voice that sounds pleased rather than excited. It lands as laid-back agreement, the kind of warm, knowing nod you give when a plan finally clicks or someone says exactly what you were thinking. It works as a light, confident reaction rather than a loud celebration.
