Read Heart Rate on Arduino over ANT+

Hello,

I'm wondering how to transmit data form Sigma Heart Rate Monitor to arduino using ANT+ protocol.
I know there is antplus-arduino but i am not sure that i can use arduino with nrf52* chip built in, or have to buy another one standalone chip and then connect it to arduino (i.ex nano every?).

If i have to buy arduino and chip separetly, then how to connect them?
