Abstract
It has been ten years since the Higgs boson discovery by ATLAS and CMS collaborations at CERN. Since then, many measurements have been carried out to understand its nature and so far good agreement with respect to the predictions of the SM was found. Such measurements as the fiducial and differential cross sections play an important role as they test the SM predictions and probe for beyond SM contributions using a wide spectra of physical observables. In the following, both the fiducial and differential cross section measurements as well as the interpretation using the $p_{\text{T}}^{H}$ shape information are presented for the $H\rightarrow \gamma\gamma$ decay channel using the LHC full Run 2 dataset at 139 fb$^{-1}$ collected with the ATLAS experiment.
