In AULP mode, interrupts cannot be triggered.

I want the 45686 to run in low-power mode and be woken up by the WOM interrupt. However, I found that using the AULP mode does not trigger the interrupt, whereas it works normally in ALP mode. I checked page 39 of the 《TDK InvenSense ICM-45605 and ICM-45686 User Guide》and found that the current in ALP mode is 64 µA (in my test it was 75 µA, which is basically consistent). It's still a little high.
Please help me answer the following questions:

1. Is it possible to trigger the WOM interrupt in AULP mode?
2. Is the APEX power saving mode ineffective in ALP mode? I configured it, but it has no effect.
   My configuration is as follows

icm45686_write_reg(EDMP_APEX_EN1, 0x04); 
u8 buf[3] = {0x30,0x30,0x30};
icm45686_write_sram(ACCEL_WOM_X_THR,buf,3);
icm45686_write_reg(TMST_WOM_CONFIG, 0x13);

Thanks
