RAK4260 Breakout Board ATECC608A Cryptographic coprocessor

Hello, The RAK4260 Breakout Board appears to have an ATECC608A Cryptographic coprocessor, but it does not seem to be included on the schematic at https://docs.rakwireless.com/Product-Categories/WisDuo/RAK4260-Breakout-Board/Datasheet/. Can you please clarify this, and provide documentation for the connection of the ATECC608A? Thank you. Scott Wagner
