Support PostHog Session Replay 🔁

[mountainash]

👍🏼 this issue if you want Zaraz/Managed component support for PostHog Session replay

---

MC allows for mouse capture using events like (from the Demo MC), so it should be possible to capture and pass this to PostHog:

  manager.createEventListener('mousemove', async event => {
    const { payload } = event
    console.info('🐁 🪤 Mousemove:', JSON.stringify(payload, null, 2))
  })

  manager.createEventListener('mousedown', async event => {
    // Save mouse coordinates as a cookie
    const { client, payload } = event
    console.info('🐁 ⬇️ Mousedown payload:', payload)
    const [firstClick] = payload.mousedown
    client.set('lastClickX', firstClick.clientX)
    client.set('lastClickY', firstClick.clientY)
  })

  manager.createEventListener('scroll', async event => {
    console.info(
      '🛞🛞🛞 They see me scrollin...they hatin...',
      JSON.stringify(event.payload, null, 2)
    )
  })

  manager.createEventListener('resize', async event => {
    console.info('🪟 New window size!', JSON.stringify(event.payload, null, 2))
  })
``

Which can give responses like:

```json
🐁 🪤 Mousemove: {
  "event": "mousemove",
  "mousemove": [
    {
      "target": "html",
      "relativeX": 1.9908,
      "relativeY": 33.5901,
      "timestamp": 1712358765951,
      "altKey": false,
      "clientX": 61,
      "clientY": 233,
      "pageX": 61,
      "pageY": 233,
      "button": 0
    }
  ]
}

🐁 ⬇️ Mousedown payload: {
  event: 'mousedown',
  mousedown: [
    {
      relativeX: 15.2415,
      relativeY: 61.2695,
      target: 'html',
      timestamp: 1712358772696,
      altKey: false,
      clientX: 467,
      clientY: 425,
      pageX: 467,
      pageY: 425,
      button: 0
    }
  ]
}

Will probably have to reverse engineer this (or include it somehow???) https://github.com/PostHog/posthog-js/blob/main/src/extensions/replay/sessionrecording.ts

Ideal i think would be to include it but how is the question indeed, maybe @bjesus has some insights on this.

happy to help but not sure what the question is exactly
