Abstract We present preliminary results on the reconstruction of the \bjpsikl decay, where \jpsi\mumu or \epem. Using a dataset corresponding to a luminosity of 62.8±0.6\invfb collected by the Belle II experiment at the SuperKEKB asymmetric energy \epem collider, we measure a total of 267±21 candidates with \jpsi\mumu and 226±20 with with \jpsi\epem. The quoted errors are statistical only.
