on update start function ? ArduinoOTA.available() ?

[Whateverman2012]

Hi,

I saw onStart function in the esp8266 version of ArduinoOTA.
Is there a way to execute code before an update with a Nano IOT 33 ?
Something like ArduinoOTA.available() ?

Regards.

there is void beforeApply(void (*fn)(void))
it is invoked just before reset (at that moment the update is already stored in flash or SD)
