Charge indicator and BLE tag from NXP Rapid IoT Out Of The Box demo

Hello,

I see in the NXP Rapid IoT Out Of The Box demo, a Home screen with NXP logo, time, charging indicator and BLE tag.
Do you know where this information is found and if it can be used in other projects?
I think that will be fun to see in our projects the battery status, or time and date.

Thank you,
Mihai
