How do you cliam server on Synology NAS?

Hi, I have a Synology DS223j. I installed the PLEX media server for the first time today. Once it was installed i proceeded to open it up and make an account. Once i entered username and pw it displayed this message: Not authorized You do not have access to this server. You may be able to claim it by choosing “Open Plex…” from the Plex menu in the macOS menu bar or Windows system tray.

How does one do this in the Synology PLEX app? There doesn’t appear to be any menu or UI,. Anyone else get stuck here ?? thanks

No.'s 15 and 31 might be of interest to you, depending on whether your NAS is already on DSM 7 or still on DSM 6.
