If you need to use Local Storage and/or Session Storage in your application, you can use LocalStorage actions.
Click on the element you want to add Local Storage actions to and make it selected. Go to the Properties panel and select the action you need under the Local Storage heading from the drop-down list with + Add Actions.
For example, in a web application you are developing, if you want the data to be deleted when the window is closed, you can use the relevant SessionStorage action.
