TrueNAS 'App' install of Jellyfin - any tips to get Radeon 890M iGPU transcoding working?

New to Linux & TrueNAS - building home servre whilst recovering from an operation.

Jellyfin running good however transcoding using lots of CPU.

In the App Config I have
Passthrough available (non-NVIDIA) GPUs
selected

In Jellyfin Setting when I select transcode to

Nothing plays that requires transcoding. Set to none and returns to working…

My questions are:-

  1. Should this work ? If not what have I messed up?
  2. Some posts say needs a ‘Docker’ install to get working, No idea where to start as there is no ‘docker’ tab in my install

Any pointers much apprciated.
