Sorry I had to intervene here. I had the same sentiment about IDE support for Elixir from using the mediocre IntelliJ Plugin.
However... after dabbling a bit I discovered VS Code + Remote Containers Plugin (because of Docker) + ElixirLS + other minor Elixir plugins that have turned my Elixir development experience into pure bliss. I haven't used the debugger in the IDE yet but I am 99% sure it's gonna work out of the box.
Happy to try and share the setup if you want to try it out.
