## Interactions

When a user interactions with a button the following flow will happen:

- We send an interaction request to the server
- Server checks if the user can make this interaction
- If the user can make this interaction, the server will:

  * `DiscourseEvent.trigger(:chat_message_interaction, interaction)`
  * return a JSON document
  
  ```json
  {
    "interaction": {
        "user": {
            "id": 1,
            "username": "j.jaffeux"
        },
        "channel": {
            "id": 1,
            "title": "Staff"
        },
        "message": {
            "id": 1,
            "text": "test",
            "user_id": -1
        },
        "action": {
            "text": {
                "text": "How to install themes?",
