Is it possible to search multiple channels with one query?

I want to search multiple channels via the Channels.id parameter for videos with one query.For example:

My request URL is: https://youtube.googleapis.com/youtube/v3/search?part=snippet&channelId=UCSzAsgKDpNkch1eRA9w5nww%20%2B%20UCyCBf6asf89aQJaSXuAuTsg&q=Bitcoin&type=video&key=[YOUR_API_KEY]

The answer is:

{"kind": "youtube#searchListResponse","etag": "DCv8u79rz_Z5yPVlSxf2awnPWTQ","regionCode": "DE","pageInfo": {."totalResults": 0,"resultsPerPage": 0  },  }, "items": []}

Is it not possible with YouTube Search API V3 in 2022 to search multiple Channel.id's for a topic with one request?

I have already tried several combining operators.Am i doing something wrong?
