Channel query in Requests API

Currently looking to use the `query` param in the Requests API (/api/v2/requests) to ONLY return tickets created using a specific channel (for example: "native_messaging". Is that possible? Not sure how to use zendesk query in this case since it's a nested data object

The response would normally look something like this:
{
    ...
     "via": {  "channel": "native_messaging"  }
}

I've tried the following but none seem to work:

• /api/v2/requests.json?query=via:channel=messaging
• /api/v2/requests.json?query=via:messaging
• /api/v2/requests.json?query=channel:messaging

Thanks in advance for any help!
