Module development and code questions

Hi all! Hope someone can help me figure this out.

I have the Views and Groups Module installed and enabled. I want to create a view that shows all groups except for group 66. I was following these steps but I got stuck on step 6. I cannot find Group ID on the Filter Criteria. I do see group ID on the list for groups. How can I fix this? I am using Drupal 9.
