STM32L433VCT6 SAI connection to TLV320DAC3100

I want to connect the STM32L433VCT6 to the TLV320DAC3100 using SAI communication.
Where should I connect the TLV320DAC3100's MCLK, BCLK, WCLK, and DIN pins on the STM32L433VCT?

MCLK -- Master Clock

WCLK = FS = LRCK -- Word Clock = Frame Select = Left-Right Clock

BCLK = SCK -- Bit Clock = Serial Clock

DIN/DOUT = SD -- Data In/Out = Serial Data

Then, in the datasheet, you'll find to which pins are these signals connected, for the selected SAI's A or B portion (example is from a different STM32 than yours):
