How can we connect Samsung M31S to windows 10 laptop and transfer files?

Install Samsung flow in both laptop and in your smartphone to transfer files wirelessly.
Or
Install smart switch on your laptop to create backup for your phone.
Or
You can connect both the device with the data cable and change from connect to charge to file transfer from notification panel.
