Automatic Visa Revalidation for H4 I-94 extension

Both me and my wife are in the US. My wife has an unexpired i-94 and she’s on H4. But her H4 visa stamp has already expired. I received my H1 extension recently, and we had NOT filed for H4 extension along with my H1 extension.
Can my wife use my approved I-797 for H1b to re-enter the US after a shirt trip to Mexico using the Automatic Visa Revalidation rule?
Does anyone have any experience doing such a thing?

Any help is appreciated.

We have not seen many try this AVR option for I-94 extension.
