Abstract: The full set of optimised CP-averaged observables is measured in the angular analysis of the decay ${\mathrm{B}^0} \to \mathrm{K^{* 0}(892)} \mu^+\mu^-$ using a sample of proton-proton collisions at $\sqrt{s}=$ 13 TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 140 fb $^{-1}$ . The analysis is performed in bins of the invariant mass squared of the dimuon system. These results are among the most precise experimental measurements of the angular observables of the $\mathrm{B}^0 \to \mathrm{K^{* 0}(892)} \mu^+\mu^-$ decay.
