Starting Home assistant on development on mac

Hi, I’m new to home assistant. We need to implement new features in home assistant ( I.e video calling) we can write our own code on front end and backend but the problem is, I’m unable to start home assistant in dev mode on my Mac. I have followed the instruction given on website Progress:

I have started the container using dev container and its showing me whether app. I want to connect front end repo (home assistant frontend) so I can customise it. I have added frontend:
development_repo: /home/Users/abyte/Documents/Home-Assistant/frontend
In configuration.yaml file but its throwing error
I have searched everywhere but couldn’t get the solution

Try asking here: (HA devs discord chat).

i did and waiting for response
