Chromecast "entity_picture: null" when casting from plex?

Hi there,

I have Chromecast Ultra that we often stream to from our phones using plex.
When we do this, the chrome cast integration doesn’t show an entity_picture, however if we stream from something like youtube it will.

I was wondering if anyone knows if it is possible to set the “entity_picture” when casting from plex?
I have included an example of what I am talking about below:

media_content_id: 933
media_content_type: tvshow
player_source: session
friendly_name: Plex (Plex Cast - Chromecast)
entity_picture: >-
