Plex Web Player don't see DLNA renderer

Hello,

Plex is quasi fantastic on :

Distro: Linux Mint 21.3 Virginia base: Ubuntu 22.04 jammy
Plex Web Player Version#: Version 4.76.1

But :
Plex Web Player don’t see DLNA renderers
(GDM) option is on.

Plex DLNA server is Ok and i can acces it whithout PB. Detected on all DLNA devices.
What is wrong ?

Thanks for your responses.

Plex cannot act as a DLNA controller.
It can only control real Plex clients.

Ouch because it would have been perfect.
Future functionality?

Very unlikely. Any development on the DLNA side ceased years ago.
