Setting up Elixir + Phoenix repl - running mix tasks

I would like to create a Repl to develop with Elixir and Phoenix.
I created a Repl for Elixir
from the shell I was able to get the phoenix archive with mix archive.install hex phx_new
However I cannot run mix phx.new, I get the following error message:

** (Mix) The task “phx.new” could not be found

Any idea what am I missing to make it work ?

Thanks

Hey @xmenage!

Can you send me the link to your Repl so I can take a look?

Here it is:
main.exs - Hello01 - Replit

Thank you
