Overlay

I’m doing a project with a map interaction. I wanted to magnify e section of a map using one overlay, then when the magnified version pops up, i want to interact with icons who are present in the magnified version. The problem is that when i try to open another overlay over the first one, the first overlay shuts off because I used the property “when mouse leave”. Any solution if I need to put multiple overlays on top of each other without closing them?
