The CO(1-0) line emission is observed across $\sim18\,$kpc scales with a resolution of $1\,kpc$. About 78\% of the CO(1-0) luminosity traces a galaxy-size rotating disk. However, after subtracting the emission due to such rotating disk, we detect with a S/N=20 a residual emission in the central $4\,$kpc. Such residuals may trace a low velocity ($v_max=170\,km\,s^-1$) outflow. We compare the momentum rate and kinetic power of such putative molecular outflow with that of the X-ray UFO and find that its energetics would be consistent with a momentum-driven blast-wave feedback model with $P_out/P_UFO=0.3\pm0.2$. This result is at odds with the energy-conserving scenario suggested by the momentum-boosted massive molecular outflows detected in some local ULIRGs. An alternative interpretation of the residual CO emission would be a compact rotating structure, distinct from the main disk, which would be a factor of $\sim10-100$ more extended and massive than typical circumnuclear disks revealed in Seyferts. However, in both scenarios, our results rule out the hypothesis of a momentum-boosted molecular outflow in this AGN, despite the presence of a powerful X-ray UFO. Abridged
