How can I find out which pin woke me up from deep sleep?

[blinry]

After configuring multiple pins as an Ext1WakeupSource, is it possible to tell which of them woke me up from deep sleep?

In case there's no official way, can you see some workaround?

Context: I want to build a device with multiple buttons that spends most time in deep sleep. I'm on a ESP32-C6, in case that matters.

I'm assuming this is not possible?

Maybe quickly checking which pin is active after waking up is my best shot – even though that might be a bit unreliable.

IIRC in esp-idf there is a function esp_sleep_get_ext1_wakeup_status - that code could get ported to esp-hal
