How can we use a late init var declared in Component Actvity, inside Composable functions placed in a diferent kotlin file?

Question

I am building an app which needs the user to turn ON and OFF the bluetooth of the phone.To get permissions and run the bluetooth system service I have delcared the permissions and activityresult as,

class BluetoothPermission : ComponentActivity() {
    lateinit var bluetoothManager: BluetoothManager
    lateinit var bluetoothAdapter: BluetoothAdapter
    lateinit var takepermission: ActivityResultLauncher<String>
    lateinit var takeresultlauncher: ActivityResultLauncher<Intent>
    override fun onCreate(savedInstanceState: Bundle?) {


        bluetoothManager = getSystemService(BLUETOOTH_SERVICE) as BluetoothManager
        bluetoothAdapter = bluetoothManager.adapter
        takepermission = registerForActivityResult(ActivityResultContracts.RequestPermission()) {
            if (it) {
                val intent = Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE)
                takeresultlauncher.launch(intent)

File Structure

• How can I access the takerpermission variable to another kotlin file which holds a button inside Devices.kt in a composable, if the BluetoothPermission(User created Activity) is already running.

• What is the best Practice for acessing variables or should just make another activity and call it ?

• The reason I don't want to make another activity is due to fact the UI doesn't change.
