ICM-20948 FIFO burst read

I am trying to read out acceleration data in bursts using the FIFO function of the ICM-20948.
I am reading from the FIFO_R_W (0x72) register after the FIFO count reaches 4096, but when I perform a burst read of more than 30 bytes I get no response.
Is there any way to read all the FIFO buffers at once?
Please let me know.

Sorry for my poor English.
