Places are not showing up

Hello! So I am trying to use this plugin with the Google Places API to find specific store types. In the map builder, I used the Google Places dropdown menu and checked all the types of places I wanted to show on the map. In the top right of the map, it says “Loading Places” but it never actually loads anything. Is there something I need to do in order for the places to actually show up on the map? Thanks so much!
