Notifications within async callback throws an error

[mayonnaisecolouredbenz7]

panel == 1.3.2

Trying to create and destroy a notification within async function throws an error described below. Equivalent code in synchronous function works as expected. Error looks to be when calling destroy()

import panel as pn
import asyncio
pn.extension('notifications')

async def btn_fun(event):
    notify = pn.state.notifications.send(
                "Running Stuff...",
                icon='<i class="fas fa-calculator fa-spin"></i>',
                duration=0,
            )

    await asyncio.sleep(2)
    notify.destroy()
button = pn.widgets.Button(name='Click me', button_type='primary',on_click=btn_fun)
button.show()

Stack traceback and/or browser JavaScript console output
