Customized icons with input_boolean

[sagined]

Hello,

in my dashboard i want to show an input_boolean with a custumized icon.
But i did not get it run.

I have created an input in the configuration.yaml

# input for scenes   
input_boolean:
  scene_licht_an_mittel:
    name: input_boolean scene - LICHT AN MITTEL
    #icon: mdi:lightbulb-outline
    #entity_picture: /local/light-50.png

than i have add the link to the customize.yaml

homeassistant:
    customize: !include customize.yaml

in my customize.yaml i have set the icon:

input_boolean.scene_licht_an_mittel:
  etity_picture: /local/light-50.png

But in my dashboard it still shows the std. icon. If I set the “icon: mdi:lightbulb-outline” in the imput an icon is shown.
Do you see my mistake

Thanks a lot now on additional step is working:
The icon is shown in the dev-tool:

But it still does not appear in the dashboard(tried it also in the incognito mode in order to avoid caching problems)
