Google Nest Integration – OAuth configuration is incomplete

Hi, Some help needed please.

I am new to all this Home Assistant stuff and have followed this Google Nest guide to integrate Nest.

I followed this guide last week and discovered i have made a error, I had added a domain on the branding page and thus lost my connection after 7 days. Today I thought I would attempted to rectify the issue , I have deleted my old integration in HA and then created a new project.

The issue I am having is not being able to publish the app. The box is greyed out and it says I need to complete the branding page, yet as per the instructions it say to only enter App name, User support email and Developer contact email (as per my screenshot).

I am not sure what I am doing wrong any advice would be super helpful.
