Shabbos hotel door solution

[Ploni3]

Saw this on Chabad of Bahamas site about Baha Mar:
The room keys are electronic so they offer a door magnet that will attach to the side of the door and avoid it from shutting. (They are available at the check-in desk of the Hyatt)

Does anyone know if such a specific door magnet is available commercially on Amazon or the like?
