How to Enable Verify App

I installed the Adobe Digital Edition app on my Samsung Galaxy S10 Plus. Whenever I launch the app a message pops up saying:

Enable Verify Apps

Verify Apps, a Google utility to help secure your device, is not currently enabled.

The two options are Don't ask again and enable. When I tap don't ask again the message goes away and I have access to my publications. Each opens without further messages. However, when I close and reopen the Adobe Digital Edition app the message reappears. If I tap enable it takes me to the biometrics and security section of my phone. I've gone through each section and I don't see anything related to verifying apps. In addition, when I search the phone for a utility named Verify Apps it’s not found.

Does anyone know how to fix this?
