Quality API: Linking CSAT survey responses to interaction IDs in Kotlin

Trying to fetch CSAT survey results via the Quality API in our Android app. I’m calling GET /api/v2/quality/surveys?interactionId={id} but getting an empty array []. The interaction ID is definitely valid. Is there a specific delay before the survey response links to the interaction? Or do I need to poll a different endpoint like surveyResults? The docs aren’t clear on the join key.
