How can I pair a bluetooth device using bleak
I have developed a code for scanning of bluetooth devices nearby how can I pair devices.
This is a code written to scan bluetooth devices

from bleak import BleakScanner
import flet as ft


async def scan_devices(device_list, page):
    device_list.controls.clear()
    device_list.controls.append(ft.Text("Scanning for Bluetooth devices..."))
    page.update()

    devices = await BleakScanner.discover()

    device_list.controls.clear()
    if devices:
        for device in devices:
            device_list.controls.append(ft.Text(f"Name: {device.name}, Address: {device.address}, RSSI: {device.rssi}"))
    else:
        device_list.controls.append(ft.Text("No devices found."))

    page.update()


def main(page: ft.Page):
    page.title = "Bluetooth Scanner"
    page.horizontal_alignment = ft.CrossAxisAlignment.CENTER
    page.vertical_alignment = ft.MainAxisAlignment.CENTER
    page.scroll = ft.ScrollMode.AUTO

    device_list = ft.Column()

    def on_scan_click(e):
        asyncio.run(scan_devices(device_list, page))

    scan_button = ft.ElevatedButton(text="Scan for Devices", on_click=on_scan_click)
    page.controls.append(scan_button)
    page.controls.append(device_list)
    page.update()


ft.app(target=main)
