N2 - KM3NeT/ORCA is an underwater Cherenkov neutrino detector currently being built in the Mediterranean Sea. The detector is optimised for the detection of atmospheric neutrinos in the energy range from a few GeV to 100 GeV in order to study neutrino oscillations and to determine the neutrino mass ordering. The observation of oscillations of atmospheric electron and muon neutrinos into tau neutrinos is a primary physics goal during the ongoing detector construction phase, with a partially instrumented volume. The tau neutrino flux at the detector can be determined in a first step by identifying a statistical excess in the shower-like event topology compared to the expectation without oscillations. This measurement will allow to probe the standard three-flavour neutrino oscillation model. This contribution will present the sensitivity of KM3NeT/ORCA to tau neutrino appearance and report a first measurement with ORCA6, an early 5% detector sub-array for an exposure of 433 kton-years.
