Two functions of centralManager used

I am trying to code out a background refresh part of my app but there are two centralManager functions in the app.

func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
        if peripheral.identifier.uuidString == selected {
            selectedPeripheral = peripheral
            centralManager?.stopScan()
            centralManager?.connect(selectedPeripheral!, options: nil)
        }
    }
    
    func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) {
        
        print("Connected to peripheral: \(peripheral)")
        // Subscribe to disconnection events
        peripheral
            .publisher(for: \.state)
            .sink { [weak self] state in
                if state == .connected {
                    self?.isConnected = true
                } else if state == .disconnected {
                    // Peripheral is disconnected, send notification
                    if self?.isConnected == true {
                        self?.sendNotification()
                        self?.isConnected = false
                    }
                }
            }
            .store(in: &cancellables)
    }

and this is the refresh part

private func handleBluetoothMonitoring(task: BGAppRefreshTask, bluetoothMonitor: BluetoothMonitor) {
        let queue = DispatchQueue(label: "com.yourcompany.bluetoothmonitor")
        task.expirationHandler = {
            // Handle expiration of the task if needed
        }
        
        queue.async {
            // Perform Bluetooth monitoring tasks here
            if let centralManagerInstance = bluetoothMonitor.centralManager {
                        DispatchQueue.main.async {
                            bluetoothMonitor.centralManagerDidUpdateState(centralManagerInstance)
                        }
                    } else {
                        print("Central manager is nil")
                    }


            // End the task
            task.setTaskCompleted(success: true)
        }
    }

Is there a way to solve this? Thanks!
