How to program BlackBoard Artemis for BLE?

I found some tutorials online about using <SoftwareSerial.H> but that library greys out whenever I select the correct “Blackboard Artemis” board. I am fairly new so I apologize for perhaps a noob question. I am trying to connect this arduino to my phone via bluetooh and don’t know where to start the coding process.

Unfortunately, the Arduino IDE still has only one example:

Looks like you would need to use the Ambiq SDK for more options.
