DLNA

good day, I come to the point so I have a remote disk connected to the router at home via usb I can access it through sharing enabled in the router settings, now .. how can I view the multimedia content via DLV support of omv to see them on the smart tv? what are the services that I have to activate apart from DLNA. I state that I installed openmediavault on raspberry pi 3 connected in the same router at home. if anyone can kindly address me on the solution I would be very grateful. best regards
