Hi in what scenarios in Real case scenearios I would like two tabs on the same browser on the same device for the same user to communicate with each other" ? What I could find was "Applications may need to maintain shared state or context between different tabs. For instance, in a web-based document editor, changes made in one tab should be reflected in other tabs to ensure consistency." Can you suggest any use case you might have worked on where the above is applicable
