Collecting test metadata from WebdriverIO junit reports

Added junit reporter to our WebdriverIO tests, I do see artifacts in the build:
Container 1
$CIRCLE_ARTIFACTS/
$CIRCLE_TEST_REPORTS/
webdriverio/
WDIO.xunit.chrome.latest.0-0.xml
WDIO.xunit.chrome.latest.0-1.xml
WDIO.xunit.chrome.latest.0-2.xml

But I see no visualization / CircleCI actually using these. Maybe only the note in “Test Summary” changing a bit? So no sign of actually utilizing them. Expected?

The documentation says “If you have multiple JUnit test reports from running more than one test suite or runner, you can merge them together” - so I don’t have to merge, I guess?
