**Figure Caption**

Left, top panel: ratio of the $p_{\rm T}$-differential cross section of $\rm \Omega_c^0$ baryons (multiplied by the branching ratio into $\rm \Omega^-\pi^+$) to the $\rm D^0$-meson one~ in $|y|0.5$ in pp collisions at $\sqrt{s}=13$~TeV. Right, top panel: ratio of the $p_{\rm T}$-differential cross section of $\rm \Omegac$ baryons (multiplied by the branching ratio into $\rm \Omega^-\pi^+$) to the $\rm \Xiczero$-baryon one~ in $|y|0.5$ in pp collisions at $\sqrt{s}=13$~TeV. Bottom panels: ratio of the data and models to the Catania (coalescence plus fragmentation) model~. The error bars and empty boxes represent the statistical and systematic uncertainties, respectively. The measurements are compared with model calculations (see text for details), which are multiplied by a theoretical $\rm BR(\Omega_c^0\rightarrow\Omega^-\pi^+)=(0.51^{+2.19}_{-0.31})\%$~.
