Firebase phone auth check if reCAPTCHA flow was triggered

From the docs

The reCAPTCHA flow will only be triggered when SafetyNet is unavailable or your device does not pass suspicion checks. Nonetheless, you should ensure that both scenarios are working correctly.

I want to check if the user was shown the reCAPTCHA screen so I could track it in the app analytics.

I couldn't find any way of achieving this in the docs. is there something I missed, or is this not available for now?
