Abstract: Using a data sample corresponding to an integrated luminosity of 103.7 fb $^{-1}$ of pp collisions, collected by the CMS experiment at $\sqrt{s}=$ 13 TeV in 2017 - 2018, the $\mathrm{B}^0\to\psi\mathrm{(2S)}\mathrm{K}^0_{\mathrm S}\pi^+\pi^-$ and $\mathrm{B}^0_{\rm s}\to\psi\mathrm{(2S)}\mathrm{K}^0_{\mathrm S}$ decays are observed. Measurements of their branching fractions, relative to the $\mathrm{B}^0\to\psi\mathrm{(2S)}\mathrm{K}^0_{\mathrm S}$ decay, are reported.
