Bluetooth module BM83, connect to DSP

Hi!

I have a circuit consisting of audio input from a microphone, which then gets amplified. This is then sent to a ADAU1467 dsp.

Now I would like to add a bluetooth module BM83 to the circuit but I'm new to all of this and don't really know how to connect the module to my circuit. The thing I want to achieve is that I would like to be able to choose between a bluetooth input to the dsp or a microphone input.

What parts do I need to add the bluetooth module and how do I connect them? I'm using BM83 since it is able to handle I2S which I want to have.
I already have 3.3 V and 5 V input.

Thank you!
