https://devzone.nordicsemi.com/f/nordic-q-a/124310/cmac-using-kmu-on-nrf54l15Hi Team, I&#39;m trying to calculate CMAC using the KMU on the nRF54L15, but the `psa_mac_compute()` function fails with the error code `PSA_ERROR_NOT_PERMITTED (-133)`. I need help resolving this issue. Below is the environment I used for testing.
