Suez-water integration install

Hi everybody,
As a newbie I am stuck in suez-water integration install.
This integration can’t be added by user interface, and I have to install it by adding its definition in my configuration.yaml.:
sensor:

  • platform: suez_water
    username: …
    password: …
    counter_id: …

After restarting HA I don’t see the integration installed.
I tried to install HACS but don’t find a way to install the integration.

Any help will be appreciated.

My config:
RPI 4
HAOS core-2023.12.4
