The idiomatic thing would be to use the pin name.
In this case the mic bias comes out of the chip trough a separate pin and it is up to board designer to connect it with any (or all) of the three mic pins.
Yes, exactly - you should be using the name of the pin that supplies the bias. This is how essentially all microphone biases work.
