-- Adds or removes permission settings for the specified snapshot. You may add or remove specified AWS account IDs from a snapshot's list of create volume permissions, but you cannot do both in a single API call. If you need to both add and remove account IDs for a snapshot, you must use multiple API calls.

-- | Creates a value of 'ModifySnapshotAttribute' with the minimum fields required to make a request.

-- Use one of the following lenses to modify other fields as desired:
--
-- * 'msaAttribute' - The snapshot attribute to modify.
--
-- * 'msaCreateVolumePermission' - A JSON representation of the snapshot attribute modification.
--
-- * 'msaUserIds' - The account ID to modify for the snapshot.
--
-- * 'msaGroupNames' - The group to modify for the snapshot.
--
-- * 'msaOperationType' - The type of operation to perform to the attribute.
--
-- * 'msaDryRun' - Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is @DryRunOperation@ . Otherwise, it is @UnauthorizedOperation@ .
--
-- * 'msaSnapshotId' - The ID of the snapshot.
