CreateFolderMembership
Use the CreateFolderMembership to add an asset, such as a dashboard,
                analysis, or dataset, to a folder. To use this operation, you need the member ID of
                the asset that you want to add to a folder. The member ID is either the dashboard,
                analysis, or dataset ID of the analysis, dashboard, or dataset that you want to add
                to a folder. The member ID is part of the analysis, dashboard, or dataset URL in
                Quick Sight. You can also use the ListAnalyses, ListDashboards,
                or ListDataSets operations to get the ID.
Following is an example AWS CLI command for this operation.
