The global read-only sharedStorage property returns the WindowSharedStorage object for the current origin. This is the main entry point for writing data to shared storage using the Shared Storage API.
Note: sharedStorage is not available inside workers. It is implemented by Window and is also available in shared storage worklets (see SharedStorageWorkletGlobalScope.sharedStorage, which returns WorkletSharedStorage).

Examples
window.sharedStorage
.set("ab-testing-group", "0")
.then(console.log("Value saved to shared storage"));
