Unverified apps screen is not displayed

I am creating an Android application with Kotlin.
My app uses Google Fit API to get the number of steps.
Implemented the function to authenticate the scope according to the manual.

Problem

Unverified apps screen is not displayed
※Attach images of Google Cloud Platform and device for each condition.
The test was conducted under three types of conditions.

1. Test in production environment
   I got stuck when the "Unverified App" screen was displayed.
   enter image description here
2. Test in a test environment　※Authenticate as a test user
   I was able to authenticate normally.
   ※Since you can authenticate here, I think that the scope setting and the creation of the authentication information are successful.

3. Test in a test environment　※Authenticate as a non-test user
   I got stuck when the "Unverified App" screen was displayed.
   enter image description here

Question

We would appreciate it if you could give us some information as to why the "Unverified App" screen is not displayed.
Please confirm.
