- every 15sec, there is a new call. Old events are kept and new ones are added.
In the current version, I limited the frontend flow to 20 (so if user gets a new event, the oldest is hidden)
- If a same robot has more than one post, the avatar is only displayed once, there is no horizontal line separation and the details about the date is lighter (only hours and minutes are displayed).
- removing minutes if value = 0
