We present the preliminary result from an analysis of the decay \(B^+\rightarrow K^{*+}\omega \) using Monte Carlo simulated data at Belle II. The final goal of the analysis is to precisely measure the longitudinal polarisation fraction of the vector mesons, the direct charge-parity asymmetry in addition to the decay branching fraction. A previous measurement of the decay at BaBar provides hints for deviation in the longitudinal polarisation fraction from the expected value within the Standard Model. We expect to improve the previous statistically dominated measurement using a larger sample of Belle and Belle II datasets along with improvements in the analysis strategy and systematics. This will be the first attempt to measure this decay channel using combined datasets from the Belle and the Belle II experiments.
