JS SDK: speechTranscriptsQuery returns empty transcript text for voice interactions

The speechTranscriptsQuery method in the JS SDK isn’t returning the actual transcript text. I’m filtering for voice interactions with a specific date range, but the response payload only contains metadata. The text field is null even though the analytics dashboard shows the transcript is available. Is there a specific query parameter I’m missing, or does this endpoint require a different token scope? Here’s the snippet:

const query = {
 dateRange: {
 startDate: '2024-01-01T00:00:00.000Z',
 endDate: '2024-01-02T00:00:00.000Z'
 },
 view: 'speech_transcripts'
};
client.speechTranscriptsQuery(query);
