Telegraf: How can leave a scene without command?

[thantez]

Hi
I try leave a scene in this codes :
scene.leave((ctx)=>console.log('leave')) scene.on('text',({reply})=>{ reply('bye'); leave('join'); })
And
scene.on('text',({reply})=>{ reply('bye'); },leave())
But they doesn't work.
So how can leave a stage after many instructions in a function?

I see source code and find that with ctx can do it.
ctx.scene.leave()
or
ctx.scene.leave('<sceneName>')
