Running async function in FUSION Script File

Question

I am creating a script file for to be used in fusion 360, when I try executing an async function some or other kinds of errors are sure to follow. Following is a simpler version of one of my problems:

# import Client.Client
import adsk.core, adsk.fusion, traceback
import asyncio
import math
import bleak

# Command properties
commandId = 'SetCameraAutoRotateCommand'
commandName = 'Auto Rotate Camera'
commandDescription = 'Automatically rotate the camera around all angles.'

app = adsk.core.Application.get()
ui = app.userInterface if app else None

# Global handlers to maintain references
eventHandlers = []

async def fu():
    l = await bleak.BleakScanner.discover()
    ui.messageBox("List of Devices: ")
    s=repr(l)
    # ui.messageBox("List of Devices: ")
    ui.messageBox(s)
    

def auto_rotate_camera():
    asyncio.run(fu())
    
# Command event handlers
class AutoRotateCommandExecuteHandler(adsk.core.CommandEventHandler):
    def init(self):
        super().init()

    def notify(self, args):
        try:
            auto_rotate_camera()
        except:
            if ui:
                ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

class AutoRotateCommandDestroyHandler(adsk.core.CommandEventHandler):
    def init(self):
        super().init()

    def notify(self, args):
        try:
            adsk.terminate()
        except:
            if ui:
                ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

class AutoRotateCommandCreatedHandler(adsk.core.CommandCreatedEventHandler):
    def init(self):
        super().init()

    def notify(self, args):
        try:
            cmd = args.command
            cmd.isRepeatable = False

            # Event handlers
            onExecute = AutoRotateCommandExecuteHandler()
            cmd.execute.add(onExecute)
            eventHandlers.append(onExecute)

            onDestroy = AutoRotateCommandDestroyHandler()
            cmd.destroy.add(onDestroy)
            eventHandlers.append(onDestroy)

        except:
            if ui:
                ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

def run(context):
    try:
        ui.messageBox("File #1")
        cmdDef = ui.commandDefinitions.itemById(commandId)
        if not cmdDef:
            cmdDef = ui.commandDefinitions.addButtonDefinition(
                commandId, commandName, commandDescription)

        onCommandCreated = AutoRotateCommandCreatedHandler()
        cmdDef.commandCreated.add(onCommandCreated)
        eventHandlers.append(onCommandCreated)

        inputs = adsk.core.NamedValues.create()
        cmdDef.execute(inputs)

        adsk.autoTerminate(False)

    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Here's the error message

bleak.exc.BleakError: Thread is configured for Windows GUI but callbacks are not working.

The asyncio code runs properly standalone when not run in fusion script file.
