javascript - How to retrieve a YouTube video's tags with YouTube v3 API?

Question

I want to retrieve the tags for a specific YouTube video using v3 of the YouTube API.

I'm able to retrieve a video with this request to the search endpoint, https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=1&q=cats&type=video&key={YOUR_API_KEY}.

Now I hit the video endpoint trying to get the tags for the video from the above query. https://www.googleapis.com/youtube/v3/videos?id=IytNBm8WA1c&part=snippet&key={YOUR_API_KEY}

Response,

API Explorer for this request - https://developers.google.com/apis-explorer/#p/youtube/v3/youtube.videos.list?id=IytNBm8WA1c&part=snippet&_h=3&

Even if I authorize this request I get the same results. Although, if the account being authorized owns the video it returns the tags.

How can I get the tags for the videos I own without asking the end-user to authorize their accounts? This implementation is client side with JS.

According to https://developers.google.com/youtube/v3/docs/videos/list it appears that the latest version of the YouTube API now returns tags:

https://www.googleapis.com/youtube/v3/videos?key={API-key}&fields=items(snippet(title,description,tags))&part=snippet&id={video_id}
