The Belle II experiment, located in Tsukuba, Japan, along the SuperKEKB $e^+e^−$ collider, has started to collect data in 2018 and offers many opportunities to improve our understanding of the $B$-meson decays. In particular, the $B^+\rightarrow K^+\nu\overline{\nu}$ decay has not been observed yet, it can be computed with accuracy in the Standard Model and is sensitive to new physics models. This presentation gives an overview of a novel approach used to search for this decay in the data collected by Belle II.
