Unable to install Emulated Hue

Hi,
I am new to Home Assistant and want to install the emulated Hue Add-on for the iLightShow App but I cannot install it.

My installation is:
Home Assistant 2022.11.4 Supervisor 2022.11.2 Operating System 9.3 Frontend 20221108.0 – latest

In the Addon-Store I click on the three dots and choose repository

Then I enter the url

and click on Add

Then it displays above with:

HASS Emulated Hue Add-Ons

but I cannot find it on the Addon Store / Home Assistant Community Add-ons

What do I have to do to be able to install emulated Hue?

Thanks for your support.
Regards
