Show notice to user based on User Meta

I need to show a site notice / elementor pop up (ideally render a shortcode) to specific users based on what User Meta they have. To be more specific, the user needs to activate their account (link sent via email) after registering. However, even if they don't click on the activation link they still have access to their account.

I want this notice to appear with something like Please activate your account at the top of the window.

The User Meta I am referring to is coming from Woo Germanized and is User Verification. According to the author of Woo Germanized, they are using the standard Woo Verification meta.

I'd appreciate any help/advice here!

Thank you!
