Just looking for a little bit more info on what you want to do. But it sounds like what you want to do is create a hotspot for each area of your scene where you want to display information to the user. Then you want to either use an info card or image or both, and unset the visible option. now in your hotspot, you can show the info card/image by adding a “Show” action on the objects you want to show.
You can add a duration to the show action so that they go away after a certain amount of time. you can also create a hotspot to show with the info card/image on the top right corner that can be used to close the info card, just like a dialog.
hope this helps, please post back if your situation is different or more complex
