The determination of the CKM matrix elements $|V_{ub}|$ and $|V_{cb}|$ from semileptonic $B$ decays is fundamental to improve the existing constraint on the unitary triangle. The experimental measurements, however, show some inconsistencies depending on the reconstruction approach (inclusive or exclusive) of the hadronic final states. Further experimental inputs are therefore needed to understand their origin. The Belle II experiment has just begun to provide a variety of different measurements which in the next years will be competitive with the world averages. Similarly, the LHCb experiment can deliver complementary results exploiting $b$-baryons and $B_s$ mesons.
In the following, some of the relevant results obtained with the first dataset collected at the Belle II experiment are briefly outlined.
