WUfB enabled with Update Baseline, No Notifications

Thanks Kay_Toma. Our biggest question is around the behavior as computers near our deadline. We want to communicate to our end-users what the notifications they will be seeing are going to look like before broad deployment, and I see a few examples in the https://docs.microsoft.com/en-us/windows/deployment/update/wufb-compliancedeadlines. For feature updates are users to expect a notification like the one below, or does this only occur for pending quality updates or for feature updates as well?

We have yet to catch one of these in-action, but want to make sure that our polices are configured to display notifications like these in addition to the toast notifications that we have been seeing post-install and after login. Are there registry keys we can check or scheduled tasks for these pop-ups to make sure they are being utilized?

Thanks again for your help!
