YouTube JS API v3. Get four last videos

Question

I'm trying to get the latest videos from a channel. For this I use this URL:

https://www.googleapis.com/youtube/v3/search?part=snippet&key=${apiKey}&channelId=${espacioSutilChannelID}&maxResults=4&order=date

I receive four videos, but they are not the last ones, why? How can I receive the latest videos?

The channel is this: https://www.youtube.com/@Espaciosutil/videos

The received JSON is this. It can be verified that the JSON results do not match the last videos of the channel:
