Cooker Hood Connection & Cabinet Repair

I need an experienced kitchen fitter or ventilation specialist to complete a cooker hood installation in a Dublin apartment. The Job: The hood is currently sitting in the cabinet but is not functional. The management company says some apartments have connections to a ventilation system and others do not (requiring internal recirculation). They haven't been helpful in providing the exact details for my specific unit. I need someone to: Investigate: Check if the existing hole in the cabinet leads to a building vent system. Connect or Convert: * If a vent exists: Connect the hood using proper ducting. If no vent exists: Convert the hood to recirculation mode (install charcoal filters/diverter). My kitchen fitter confirmed the cooker unit supports this. Finish: Neatly seal/patch the hole in the cabinet. Photos attached: View of the current hood, the cabinet hole, and the unit design.
