Refresh the page when session closed

[raz-kash]

I tried refreshing the page after session is closed with :
session.run_js('WebIO._state.CurrentSession.on_session_close(()=>{setTimeout(()=>location.reload(), 40000})')
but I kept getting the next error:

You need add the session.run_js() call inside your pywebio app function, like:

def main():
    session.run_js(...)

start_server(main, ...)

My code is running from flask
