PLEX entity_picture send on Telegram

Have an automated created where I see who is watching what on the Plex server.
I’d like to get the entity_picture from the current movie sent to me.
How can I do that?

Automation:

alias: “Plex Nachricht”
initial_state: ‘on’
hide_entity: false
trigger:
platform: state
entity_id: sensor.plex
condition:
# condition: template
# value_template: ‘{{states.sensor.plex.attributes.johination}}’
condition: numeric_state
entity_id: sensor.plex
above: 0
action:
service: notify.telegram_homeassistant
data_template:
message: >
{% for attr in states.sensor.plex.attributes %}
{%- if not attr==“friendly_name” and not attr==“unit_of_measurement” and not attr==“icon” -%}
{{attr}} schaut: {{states.sensor.plex.attributes[attr]}}
{%- endif %}
{%- endfor -%}
