The total and differential Higgs boson production cross-sections are measured through a joint analysis of the $H \rightarrow ZZ^* \rightarrow 4\ell$ and $H \rightarrow \gamma \gamma$ decays. The results are based on a dataset of 139 fb$^{-1}$ of proton$-$proton collisions recorded by the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of 13 TeV. The measured total Higgs boson production cross-section is 55.5$^{+4.0}_{-3.8}$ pb, consistent with the Standard Model prediction of 55.6$\pm 2.8$ pb. All results from the two decay channels are compatible with each other, and their combination agrees with the Standard Model predictions. \\ A joint interpretation of the measured Higgs boson fiducial transverse momentum distributions is performed and combined with measurement results from $H \rightarrow b\bar{b}/c\bar{c}$ to probe the Yukawa couplings to the bottom and charm quarks.
