Place it just after the visual gag, then follow with Chipmunk Laugh for a bigger reaction, or let Awkward Crickets take over when the joke falls flat. Keep it as a beat between lines of dialogue, not as the closing sound of a scene.

This is a brief, airy hahaha lasting about a second, a small puff of laughter rather than a big belly laugh. It feels light, cheeky and a little mischievous, the kind of giggle that lands when something is only slightly funny. Its quick, soft delivery makes it easy to drop into a joke without stealing the moment.
