User-processes should push a common arguments struct and [[#UiSettings]]. Official sw can optionally push an additional storage from [[Applet_Manager_services#CreateTransferMemoryStorage|CreateTransferMemoryStorage]] with flag=0 using an input buffer when that input buffer is not NULL, however sdknso itself doesn't use this besides a wrapper func which sdknso itself doesn't call. After launching the applet and waiting for it to finish, on success the output storage [[#UiReturnArg]] should be popped.
