Unable to send video stream to ios phone

I have managed to get home assistant to respond to a button press on an esp32-cam device and send a notification to my iphone. However. I also wanted to send the video feed from the camera. However, I get an error on my phone saying that /api/camera_proxy_stream/camera.doorbell is missing.
If I look in the developer tools config for the camera entity it shows
friendly_name: camera.doorbell
entity_picture: >-
/api/camera_proxy/camera.camera_doorbell?token
However, if I look in the File Editor directory astructure, under api, it does not have a directory camera_proxy.

My call service Action is
title: ‘Knock,Knock’
message: Someone is at the door
data:
attachment:
content_type: jpeg
push:
category: camera
entity_id: camera.doorbell

I can’t see where I have gone wrong !!
