There’s a much easier way to enable it in countries where its still not out.
Try copy and paste this url “x-apple-health://HearingAppPlugin.healthplugin/HearingTest” to trigger the hearing test in iOS Safari.

For the millionth time:
This does not enable hearing aid function in any way. You can take a test. You can see the results.
You cannot use those results to change for the AirPod functions. You still will not have access to the separate Hearing Aid functions and settings.
Taking a test has nothing to do with enabling the hearing aid functions that many bought their AirPods to do.
