Prototyping Help!

Hello,

I am a Uni student trying to use Figma for an assignment, and I am struggling with prototyping an interactive “like” button into my frame.

The button itself is a flow frame, but whenever I try inserting it into my iPhone frame, the flow is deleted and the entire flow becomes visible in present.

I just need the button to work on the screen, and I have no idea how to do it. Plz help 😦
