I finally bought the Philips magnetic smartphone holder from Rakuten, which I'd been interested in for a while. It's a great product that offers 15W wireless fast charging, has a stand that's freely bendable, and can be attached anywhere with Velcro.

The mounting location is on the side of the console box in front of the shift lever on the dashboard. An additional piece of Velcro is included, so it can be mounted in other locations as well.

It's in a perfectly convenient position to operate from the passenger seat.
