Get campaign performance by device - API endpoint

I’m trying to get the performance by device of my campaigns (the ratio of mobile / desktop users) from the API. This statistic is available in Klaviyo UI when clicking on a campaign in the Deliverability tab:

From the doc, the campaign-values-reports endpoint of the Reporting API seems to return statistics of a given campaign. I can access the click rate, open rate and a lot of other data but I didn’t find anything about the performance by device.

I feel like this should be possible since the data exists and is accessible through Klaviyo UI. Do you know how I can access this data through the API?
