Instagram Music Library API - Reels Audio Search

Instagram lets Reels use audio assets from its audio API. In bundle.social, you search for an audio asset first, then pass its audio_id as data.INSTAGRAM.musicSoundInfo.musicSoundId when creating a Reel.

Instagram audio search and Reel audio publishing require the Instagram account to be connected through Facebook Login. Direct Instagram OAuth (instagramConnectionMethod: "INSTAGRAM") cannot use this feature.
