This allows for precise measurements of hadronic $B$ decays, which is essential to test Quantum Chromodynamics (QCD) and refine theoretical models. This also helps improve simulation accuracy. We present results for the $B$ to hadronic decays such as $B^- \to D^0 \rho^-$, $B \to DK^{*}K_{(s)}^{(*)(0)}$ and the first Belle and Belle II combined $\phi_3$ measurement. 000004582 8560_ $$fph21resch11018@iith.ac.in 000004582 8564_ $$uhttps://docs.belle2.org/record/4582/files/BELLE2-CONF-PROC-2024-025.pdf
