Need Erlang's instrument module in a release
I find that a deployment built with mix release does not contain the :instrument module. I am stuck on an older version of Elixir here (1.10), for… reasons. But the instrument module is available when running MIX_ENV=prod iex -S mix run --no-halt (also when running dev).
It’s not an application, so can’t add it to other_applications. I don’t think it is a dependency of some other application: instrument — OTP 29.0.2 (runtime_tools 2.4)

There are many things which are not obvious in the Erlang documentation.
