[QUESTION] How to enter a scene without context but with chatId

I’m trying to enter a scene because a server side event happened. I have the chatId but no context, since the user didn’t talk in the chat.

How should I enter the scene ?

Here’s a little bit of code:

const PrivateMessage = new Scene('PRIVATE_MESSAGE')
PrivateMessage.enter((ctx) => ctx.reply('echo scene'))
PrivateMessage.leave((ctx) => ctx.reply('exiting echo scene'))
PrivateMessage.command('back', leave())
PrivateMessage.on('text', (ctx) => ctx.reply(ctx.message.text))

this.bot = new Telegraf(this.options.token, {username: this.options.username});
const stage = new Stage([PrivateMessage]);
this.bot.use(session());
this.bot.use(stage.middleware());

ipcMain.on('TelegramNotificationRequest', (ev, obj) => {
  Stage.enter(obj.type); // 'PRIVATE_MESSAGE'
})

When the TelegramNotificationRequest happens, I would like to enter the scene to ask the user what does he want to do.

Is it possible ?

Hello, isn’t still possible to enter into the scene during some server event? I think it is a very useful case and is there any way to realize it? So I need to enter into the scene, then send a message to the user and wait for a response.

Guys, enter can’t be called without context. If you want to achieve external control for user, you need to store this event and use it only when you have any update from user.

this.bot = new Telegraf(this.options.token)
const stage = new Stage([PrivateMessage])
stage.on('message', (ctx) => {
  if (database.eventPending(ctx.chat.id)) {
    return ctx.scene.enter('blabla')
  } else {
    return next()
})
this.bot.use(session())
this.bot.use(stage.middleware())
