ULP wakes ESP32

Dear all,

Our set-up: ESP32, LiPo battery, load cell, HX711.
ESP32 is in deep sleep.
We want to wake CPU up when the ULP sees a change on the load cell >10 grams and smaller <200grams.
Objective is to save battery life.

Is this possible?
If so: how?

Hope there is a solution!
Best regards Fred
