I have zero idea what the terminology is in English, but it’s connected to what translates to something like an “ejector line” that’s either built into the faucet or purchasable as a separate adapter. Here’s a diagram I found for Oras Bidetta as an example:

Here’s what it looks like under my sink (sorry about the awkward angle, didn’t want to remove a shelf so I had to shoot blind)

With the line on the left being the one for the hand shower, and it just connects into the faucet via a built in ejector thingamajig.
