Error when trying to add BLE presence code to unit with ld2450 radar

Hi all.
I have an Apollo MTR-1 with CO2 sensor. I was trying to add some code to make it a bluetooth tracker as well. I followed the guide as posted by homeautomationguy where you add the below code to be picked up by Format-BLE-Tracker:

mqtt:
  broker: 192.168.0.110
  port: 1883
  username: myusername
  password: mypassword
  discovery: true

# Adding external component to build:
external_components:
  source: github://formatBCE/ESP32_BLE_presense@main

# System time config - required for precise timestamps, used in integration:
time:
  - platform: homeassistant
    id: homeassistant_time

# Initializing it:
esp32_ble_presense:
  area: "Command Centre" # Replace this with your room name
  time_id: homeassistant_time

However I get an error referring to the mm-wave sensor, specifically mentioning the component is not found. It works fine without the code so it definitely is ok. This code was supposed to be able to be added to devices already doing something else but obviously something doesn’t gel well.

Can anyone please point me in the right direction? I’m still learning al this so just going through random docs hoping I’ll pick something up is not working.
Thanks

Did you use the provided samples as a base?

I didn’t touch the original install (too scared to in case I stuffed something up) but I see it is referencing the github package you linked to. I just copied the code I snipped in my original post below what is shown here.
