No significant deviation from the Standard Model is observed and upper limits are placed on the production cross-section times branching ratio to two photons as a function of the resonance mass. %R 10.1016/j.physletb.2021.136651 %U https://arxiv.org/abs/2102.13405 %U https://doi.org/10.1016/j.physletb.2021.136651 %P 136651-19pp
