Remote access to Plex on Synology NAS via Tailscale

[Enquiries]

Can you possibly explain the process by which I can remotely access Plex which is installed on my Synology NAS (which I usually accessed on my PC via my home network) so I can instead use my Android phone to access Plex when outside of my home network via Tailscale. The few YouTube videos about this are concerning Plex hosted on a PC rather than via a NAS.
I have Tailscale installed on my laptop and on my Android phone and would really appreciate a step by step guide.
