Synchronize leaflet map on two different browser tab

I am using leaflet, javascript, and react. The leaflet has a plugin called Leaflet sync.
This plugin sync two or more map demo. I want to synchronize the map in two different browsers’ tabs. Here is my code so far Code Link.

How can I use mapA.sync(mapB) to sync maps in two different browsers’ tabs. I think I cannot since both are isolated from each other.

How can I achieve the same functionality as in leaflet sync but with different browser tabs?
