title: Telegraf.js pass data from button to a function that handle a WizardScene
body: <p>I need to pass some data retrieved from a Database.</p>
  <p>When i click into a button i send a private message to the user who have cliecked. I need to pass some datas from that button, to the message sent. Because, into that message i have an other button that starts a WizardScene. SO how can i do to pass data? Thank you.</p>
  <p>Here is my code.</p>
  <p>This is into a function that post a photo with a description and with a callbackup button.</p>
  <pre><code>my function() {
  ...
  let productId = //obtain from a db;
  await bot.telegram.sendPhoto(
        channel_id,
        { source: filepath },
        {
          caption: description.join(&quot;\n&quot;),
          parse_mode: 'MarkdownV2',
          reply_markup: productButtons.reply_markup
        }
      )
    return productId;
  ...}
  </code></pre>
  <p>and the button is:</p>
  <pre><code>const productButtons = Extra.markup((m) =&gt;
    m.inlineKeyboard([
      [m.callbackButton('TEST', 'test_btn')],
    ])
  )
  </code></pre>
  <p>when someone clicsk on it, it sends a message on a private user with this:</p>
  <pre><code>bot.action('testa_btn', (ctx) =&gt; {
      console.log('testa')
      let text = `My text about ${productId}`
  
      ctx.telegram.sendMessage(ctx.from.id, o_functions.escapeReplace(text), {
        parse_mode: 'MarkdownV2',
        reply_markup: startBtn.reply_markup
      })
      
    });
  </code></pre>
  <p>this sends a text where i need to write my productid, and an other button where i start my wizard scene:</p>
  <pre><code>const startBtn = Extra.markup((m) =&gt;
    m.inlineKeyboard([
      [m.callbackButton('START', 'start_btn_wizard')],
    ])
  );
  
  bot.action('start_btn_wizard', (ctx) =&gt; {
      return ctx.scene.enter('super-wizard');
    })
  </code></pre>
  <p>So how can i pass my productId variable, first to the button TEST, then to the wizard scene? I need to use it on the Wizard on the user dialogue.</p>
  <p>THank you</p>
