Unable to use tamper event detection (TAMP) with Trustzone activated in stm32U575?

[ZKRAC.1]

Actually, I'm trying to use passive tamper detection with trustzone activated in stm32U5. I'm using pushbutton to simulate the tamper and I want to to toggle an LED as a response, it works when I configure the tamper as non-secure, and the LED is configured in both scenarios (secure or non-secure), but unfortunately when I try to configure the tamper as secure it doesn't work and it's unable to generate interruption in the secure world, I'm wondering if we can use the tamper in the secure world, according to the documentation the TAMP is fully securable by trustzone, but when I tried it I didn't get any interruption and the tamper was not detected.

Thank you.

I see that you asked almost the same question here.
