This is my script, and I am using the same localhost in my API OAuth as well. What is happening?
The page remains stuck on this verification forever without ever picking the Key:

We're attempting to generate a link for authentication to my google account for verification.The script fetches daily analytics (views, likes, dislikes, average view duration) from the YouTube Analytics API for a specified YouTube channel. It uses OAuth2 credentials from a credentials.json file, and if necessary, guides the user through the authentication process. The retrieved analytics data is then saved to a CSV file named youtube_analytics.csv.
