Integration Legrand Home + Control

Configuration
1

Hi all, I’m integrating Legrand Home+Control into HA via api.
I’ll explain exactly what I did so that you understand if I missed a step.
registered as per Legrand Home+ Control - Home Assistant on legrand website
created a new app by inserting in the “First Reply Url” the external HA web address via duckdns example https://myaddress.duckdns.org:haport, approved by Legrand and sent Client ID and Secret ID via email.
placed in the configuration.yaml file

home_plus_control:
  client_id: 
  client_secret: 
  subscription_key: my mail login legrand

I restart, I try to download the “Legrand Home + Control” integration I start and it opens an external web page with this code/error

{
  "error": "invalid_request",
  "error_description": "The reply url host my.home-assistant.io doesn't match with the ones configured on the application"
}

Where am I doing wrong?

Hello. I am also trying to integrate Home Control.
In the step that you got stuck, you have to put as URL the one that is telling you the message “my.home-assistant.io”

I’m stuck on the following. The integration is already there according to HA but I can’t find any Legrand device or entity
