plex via colima (broadcast discovery UDP)

[fuesec]

I want to run plex via docker compose through colima on macOS Sequoia 15.4. You can see my setup below. If I choose bridged mode I can reach plex web UI fine from macbook running colima via http://localhost:32400/web and any other machine on the local network via http://{fqdn-of-macbook}:32400/web. However my TV running plex cannot find media library although GDM (plex custom protocol for broadcast discovery via UDP) is turned on. If I change network mode to host in docker compose file I can only reach plex via http://{colima ip address}:32400/ and not on any other device on local network nor can the plex on my tv find the library. If I am in bridged mode and enter http://{local-ip-address-of-macbook}:32400 under "Custom server access URLs" plex on my tv can find my media library. Do you have any advice of how I can make this work without entering the ip manually in plex server settings? What network mode would I have to choose and what kind of colima settings to get my tv to discover my media library in the most straightforward way?
