CSR USB bluetooth dongle not working on Big Sur

I purchased a cheap USB bluetooth dongle from amazon.
the system report on USB tab
from Bluetooth tab

it scans and finds the avaliable devices but when i try to connect it loads and fails to connects and sometimes shows to enter the bluetooth pairing code but i connect my tws they don't have any code.
i want to use my TWS for Zoom meetings but it is not connecting. I have installed the IntelBluetoothFirmware.kext and BlueToolFixup.kext but still same.
Please help me out.
