Problem connecting to Azure Service Bus using rabbitmq-amqp1.0-client - azure

Question

I'm trying to connect Azure Service Bus (AMQP 1.0) using this erlang client: https://github.com/rabbitmq/rabbitmq-amqp1.0-client
The elixir wrapper library https://github.com/pma/amqp doesn't seem like using AMQP 1.0. So I'm trying to use the erlang client directly.
I did the following:
git clone https://github.com/rabbitmq/rabbitmq-amqp1.0-client.git
cd rabbitmq-amqp1.0-client
make
make shell
Then I created a config as per the README file at https://github.com/rabbitmq/rabbitmq-amqp1.0-client
OpnConf = #{address => Hostname,
port => Port,
hostname => <<"abc-shankardevy.servicebus.windows.net">>,
tls_opts => {secure_port, [{versions, ['tlsv1.1']}]},
container_id => <<"test-container">>,
transfer_limit_margin => 100,
sasl => {plain, User, Password}}.
When I try to open the connection as in the README, I get the following error. I'm not able to follow the erlang error message. Any help is appreciated.
{ok, Connection} = amqp10_client:open_connection(OpnConf).
** exception exit: {noproc,{gen_server,call,
[amqp10_client_sup,
{start_child,[#{address =>
'abc-shankardevy.servicebus.windows.net',
container_id => <<"test-container">>,
hostname => <<"abc-shankardevy.servicebus.windows.net">>,

sasl =>

'mykey'},

infinity]}}
in function gen_server:call/3 (gen_server.erl, line 223)
in call from amqp10_client_connection:open/1 (src/amqp10_client_connection.erl, line 110)

Try "starting" the application first:
application:ensure_all_started(amqp10_client).
It's complaining about not finding a certain process (noproc), namely the one called amqp10_client_sup. This process is started when the application is started, by this piece of code:
-module(amqp10_client_app).
-behaviour(application).
-export([start/2,
stop/1]).
start(_Type, _Args) ->
amqp10_client_sup:start_link().
