Sensortile.box mlc data (csv file) capture for unico gui offline mode

Hi! I have sensortile.box. I want to capture (lsm6dsox)mlc data for unico gui. I followed the steps which are in https://github.com/STMicroelectronics/STMems_Machine_Learning_Core/tree/master/configuration_examples/example_1_sensortilebox_stble_unico. Sensortile.box never save data like yoga example. How can i capture mlc data as csv files? By the way my smart phone app version is 4.14.4(76). But in example mobile app version(4.6.4) is different. Is it important? Is the firmware important. My sensortile.box has orginal firmware. Is it necessary any other firmwares like datalogextended etc.?
