  IceTop, the surface array of the IceCube Neutrino Observatory, consists of
162 ice-Cherenkov tanks distributed over an area of 1km$^2$. Besides being used
as a veto for the in-ice neutrino detector, IceTop is a powerful cosmic-ray
detector. In the upcoming years, the capabilities of the IceTop array will be
enhanced by augmenting the existing ice-Cherenkov tanks with an array of
elevated scintillator panels and radio antennas. Combining the data obtained
from the different detectors will improve the reconstruction of cosmic-ray
energy and primary mass while reducing the energy threshold and increasing the
aperture of the array. In January 2020, a prototype station consisting of 8
scintillation detectors and 3 antennas was deployed at the IceTop site. The
prototype detectors are connected to one data-acquisition system and the
readout of the radio antennas is triggered using the signals from the
scintillators. This allows us to regularly observe secondary air shower
particles hitting the scintillators, as well as the radio emission of
high-energy air showers. In this contribution, we will discuss the results
obtained from the prototype station in the past year, present the first
cosmic-ray air showers measured with this prototype station, and show how the
observations with the different detector types complement each other.
