                      $\to$$\mathcal{AA}$, with $\mathcal{A}$$\to$$γγ$ is
                      presented, using events with a semi-merged topology. One of
                      the hypothetical particles, $\mathcal{A}$, is assumed to
                      decay promptly into a semi-merged diphoton system
                      reconstructed as a single photon-like object, while the
                      other $\mathcal{A}$ decays into two resolved photons. The
                      search is performed using proton-proton collision data
                      collected by the CMS experiment at $\sqrt{s}$ = 13 TeV,
                      corresponding to an integrated luminosity of 138 fb$^{-1}$.
                      The data agree with the standard model background
                      expectation. Upper limits are set on the product of the
                      Higgs boson production cross section and the branching
                      fraction, $σ$(pp $\to$ H)$\mathcal{B}$(H
                      $\to$$\mathcal{AA}$$\to$ 4$γ$), which range from 0.264 to
                      0.005 pb at 95\% confidence level, for $\mathcal{A}$ masses
                      in the range 1 $\lt$ $m_\mathcal{A}$ $\lt$ 15 GeV. These
                      limits are the most stringent to date in the 1$-$5 GeV
                      $m_\mathcal{A}$ range.},
