How to add the hfp/hsp profile based speaker for input (speech recognition)and output simultaneously?

Question

I m trying to make kinda type of assistant out of my raspberry pi 3 b+ model and so bought  this
Speaker . So that I can use it to give audio input as well as get the output at the same time .
But I'm totally confused how to connect it !! Even I'm not sure whether I have bought the right speakers or not ?
Basically I saw it supports call answering that's why I bought it.

So please guys instruct me how to do it or  anyone suggest me  the right speaker (if that is not worth suitable) .
I'm a beginner , any help is highly regarded !
