Divider In Vertical Stack

Configuration
1

I can’t seem to get the divider to work in a vertical stack, and ideas?

I keep getting the message:

Unknown type encountered: divider.
Type: divider

Home Assistant 0.107.5

type: vertical-stack
cards:
  - type: entities
    title: Section 1
    entities:
      - light.light_1
      - light.light_2
      - light.light_3
  - type: divider
  - type: entities
    title: Section 2
    entities:
      - light.light_4
      - light.light_5
      - light.light_6

It’s a special row element for the entities card. Not the vertical stack card.

Like this:

type: vertical-stack
cards:
  - type: entities
    title: Section 1
    entities:
      - light.light_1
      - light.light_2
      - light.light_3
      - type: divider
  - type: entities
    title: Section 2
    entities:
      - light.light_4
      - light.light_5
      - light.light_6

Ah! So simple, thanks!
