YouTube Data API is not returning comments from Community tab

Hi YouTube Data API Team -

The commentsThread endpoint (https://youtube.googleapis.com/youtube/v3/commentThreads) is not returning comments from the Community tab in YouTube.

I've debugged this extensively, trying just the channelId parameter instead and the comments from the Community tab simply do not return on the API call.

The channel ID is UC7kCeZ53sli_9XwuQeFxLqw and the querystring parameters I send to the commentsThread endpoint on an HTTP GET are as follows:

part: snippet,repliesallThreadsRelatedToChannelId: UC7kCeZ53sli_9XwuQeFxLqwkey: {YT_API_KEY}maxResults: 100

Is there a different API endpoint for Community tab post comments/replies or is there a bug in the endpoint?

Thanks!
