Need help to extract telegram message arguments

I try to share links to my lg webos tv from telegram.
When i sent to bot command /lg65 google.com, HA must call this event:
entity_id: media_player.lg_65
command: system.launcher/open
payload:
target: ‘google.com
I create this automation:
Trigger:
‘platform: event
event_data:
command: /lg65
event_type: telegram_command’
Event:
‘service: webostv.command
entity_id: media_player.lg_65
data:
command: system.launcher/open
payload:
target: ‘url from message’’ - how properly set this argument?
