Where is my mistake in customize.yaml

Where is my mistake in customize.yaml
In my configuration.yaml i write customize: !include includes/customize.yaml
My file customize.yaml

customize:
  device_tracker.imac_vadim:
    friendly_name: iMac — Вадим
    icon: mdi:laptop

When i check configuration from starting i see " Configuration warnings

Integration error: customize - Integration ‘customize’ not found."

Customize should be under homeassistant: and one level indented:

homeassistant:
  customize: 
    device_tracker.imac_vadim:
      friendly_name: iMac — Вадим
      icon: mdi:laptop

I think the content of the customize.yaml file should read;

device_tracker.imac_vadim:
  friendly_name: iMac — Вадим
  icon: mdi:laptop
