As we want to retrieve as many comments as possible, we have to proceed video per video, as [`3F8dFt8LsXY`](https://www.youtube.com/watch?v=3F8dFt8LsXY) for instance has comments but using YouTube Data API v3 CommentThreads: list endpoint with `allThreadsRelatedToChannelId` filter returns for `UCWIdqSQekeGmUWlSFeCiEnA`:
```json
{
"error": {
"code": 403,
"message": "The video identified by the \u003ccode\u003e\u003ca href=\"/youtube/v3/docs/commentThreads/list#videoId\"\u003evideoId\u003c/a\u003e\u003c/code\u003e parameter has disabled comments.",
"errors": [

"domain": "youtube.commentThread",
