Factor last used timestamp

Referencing: Factors | Okta Developer

I can use the factor report from the admin console to get this:

MFA Factor Last Enrolled_ISO8601 Last Used_ISO8601
Google Authenticator 2020-08-13T17:16:34.000Z 2022-01-13T16:14:50.000Z

But I can’t seem to get the ‘last used’ from the API.
There is
created : 2022-05-01T01:48:38.000Z
lastUpdated : 2022-05-01T01:48:38.000Z

But not last time used! Harrumph!
Want to run a report to see all enrolled factors and their last time used but alas? No way to do so via api?
