Topic: RemoteXY lib version 4.1.4 compiler waring about deprecated

I get the following compiler waring when programming an ESP32 board and using BLE to connect to my phone. Code still works, but when will issue resulting in warnings be corrected?
Warning is:
libraries\RemoteXY\src/RemoteXYStream_BLEDevice.h:74:14: warning: 'BLE2902' is deprecated: NimBLE does not support manually adding 2902 descriptors as they are automatically added when the characteristic has notifications or indications enabled. Get/Set the notifications/indications properties of the characteristic instead. This class will be removed in a future version. [-Wdeprecated-declarations]
   74 |     BLE2902 *ble2902 = new BLE2902();

Could you please tell me what board you're using? What version of ESP32 do you have? I tested it on Espressif Systems version 3.3.1. I don't have this message.
Could you share the full compiler output?
