Support Request: Devices not found via BLE on Raspberry PI 4
### Describe Your Problem

I try to connect a Bot via BLE. I think i have installed the necessary requirements as described here.
https://github.com/homebridge/noble#prerequisites

If i use the native Bluetooth scan from my PI the Raspberry found BLE devices. But in the Homebridge no entry that a device is detected. I thought i dont need to add the API Token as in that case the Plugin uses my Switchbot account and adds all devices. Therefore i have not entered it in the configuration and the below log pops up. Any ideas?

Do i need to install  @abandonware/noble ? If yes how to add this line from the description? 
`const noble = require('@abandonware/noble');
`
