Nest doorbell notification on TV

I have a Nest doorbell (wired) and would like to show the camera image on android TV when the person detection sensor is triggered.

The code for image path shown below works well to show the image though the HA app, but it does not work when used with “Android Notifications for TV” service.

It appears that the problem is related to thumnails from doorbell being saved in gif or mp4 format, which “Android notification for TV” cannot use.

Is there another way to grab a screenshot from the nest doorbell (wired) or show mp4 files on TV?

service: notify.android_tv_fire_tv
data:
  message: Doorbell Pressed
  title: Someone pressed the doorbell
  data:
    image: >-
      /api/nest/event_media/{{ trigger.event.data.device_id }}/{{ trigger.event.data.nest_event_id }}/thumbnail
