Nintendo Switch on laptop?

How do you connect a Nintendo Switch to the laptop? Because a friend of mine bought a laptop and doesn't know how to connect the switch to the laptop

What does he want to connect? Nothing is done via Hdmi, most Hdmi connections on laptops are only outputs and not inputs.

What do you hope for from this?

Do you want to play on the laptop? Record the switch? This is not possible natively, you need a capture card for this - if you have a normal switch and not the Lite. With the Lite you have no video transmission via USB
