XIAO BLE (nrf52840) connect to JDY-23 BLE module - arduino?

Hi I would like to connect the XIAO BLE to a JDY-23 module. (I was able to do with XIAO ESP32C3) Arduino using BLEDevice.h. But it doesn’t work for me with XIAO BLE.
Which library should be used (I tried the bluefruit - but couldn’t find how to use the specific service - I found examples only for UART, but the JDY-23 has a unique UUID for service)
and it doesn’t work for me.I think the XIAO has a nice board with a terrible SW support - or am I lame?
