First measurements on charmless $B$ decays at Belle II

We report on the first Belle II measurements of branching fractions and CP-violating charge asymmetries in charmless $B$ decays. We use 34.6 fb${}^{-1}$ from electron-positron collisions collected in 2019 and 2020 at the $\mathrm{{\rm Y}}(4S)$ resonance. The results are compatible with known values and show performance already comparable with Belle.
