How to set target location for Discovery-style personal transporter?

The only explanation is that the device can, to a certain degree, read minds. See the clip from ST:DIS, S03E06:

Linus appears

Linus: Oops, didn't expect to... this isn't the mess hall. Hmm. Bye.

Linus disappears

Paul Stamets: Linus, don't do that.

Linus: Sorry, new badge.

Linus taps badge and disappears.

I think, specially interesting is the second appearance of Linus. In both others, he mentions where he wanted to go before transporting again. It can certainly be assumed that the voice recognition in the 30th century is good enough to recognise that This is not X by an immediate transport request is the desire to go to location X.

However, in the second scene, Linus appears and mentions with no word where he wanted to go. If he'd entered the correct location in the first place, it is safe to assume the transporter is good enough for him to arrive there. So, control with your mind would explain how he could've transport in and out without mentioning where he wants to go. That would also explain his initial problems. Wanting to go to a location A but having location B in mind (for whatever reason). The transporter would have issues identifying the correct location and send him to the wrong one.
