How to create a pop up button when scrolling past a certain date?

Hello there, I’m a newbie to Figma, only started using it a year ago. Currently I’m working on an app and I need to integrate a pop up button for (show today) when when user scrolls content past (today’s) journal entry.

I also need to incorporate a pop up notification for a daily streak. Any idea how to do this? I’m not familiar with the terminology used for this method. Please help, and thank you! :slight_smile:

Here is the link to the screen:
