IceTop, the surface array of the IceCube Neutrino Observatory, consists of162 ice-Cherenkov tanks distributed over an area of 1km$^2$. Besides being usedas a veto for the in-ice neutrino detector, IceTop is a powerful cosmic-raydetector. In the upcoming years, the capabilities of the IceTop array will beenhanced by augmenting the existing ice-Cherenkov tanks with an array ofelevated scintillator panels and radio antennas. Combining the data obtainedfrom the different detectors will improve the reconstruction of cosmic-rayenergy and primary mass while reducing the energy threshold and increasing theaperture of the array. In January 2020, a prototype station consisting of 8scintillation detectors and 3 antennas was deployed at the IceTop site. Theprototype detectors are connected to one data-acquisition system and thereadout of the radio antennas is triggered using the signals from thescintillators. This allows us to regularly observe secondary air showerparticles hitting the scintillators, as well as the radio emission ofhigh-energy air showers. In this contribution, we will discuss the resultsobtained from the prototype station in the past year, present the firstcosmic-ray air showers measured with this prototype station, and show how theobservations with the different detector types complement each other.
