datastore:",flatten" saves data as flattened in data store. The property names becomes flattened with . like SignerData.Id as property name but when it's read from data store, how can I map it back to struct? It fails throwing an error like:
SignerData.Id could not be found as a key in struct. Error: No such struct field.
