We report the first determination of the Cabibbo-Kobayashi-Maskawa matrix elements |V₂ₒ| and |V₂₃| from a global fit to data from inclusive and sum-of-exclusive charm decays. Simultaneously, the heavy quark expansion parameters are determined, and they are in good agreement with results from the literature, validating the robustness of this work. With the current precision, our determined value for |V₂ₒ| is consistent with the world-average value extracted from exclusive charm decay processes, while a tension of approximately 3σ is observed for |V₂₃| when compared to its exclusive world-average counterpart.
