Not getting access to agents functions as expected

I'm not sure if this is an issue of me not understanding how Requires.jl works; it not being implemented correctly in this repo; or something else, but I have a MWE where I would expect to get access to the agents/ functions from InteractiveDynamics, but for some reason they don't get loaded.

If I generate a new package "TestMod", activate the environment, and add only "InteractiveDynamics" and "Agents", I get a Project.toml that looks like this:

name = "TestMod"
uuid = "43a1a35d-8048-4c0f-b05e-6c9f886ced7d"
authors = ["me <me@myemail.com>"]
version = "0.1.0"

[deps]
Agents = "46ada45e-f475-11e8-01d0-f70cc89e6671"
InteractiveDynamics = "ec714cd0-5f51-11eb-0b6e-452e7367ff84"

Then if my TestMod.jl file is simply:

module TestMod;

using Agents
using InteractiveDynamics

@show(names(InteractiveDynamics, all=true))

import InteractiveDynamics.agent2string

end

And I run:

(@v1.8) pkg> activate .
julia> using TestMod

I would expect to get access to all the functions within the src/agents/ files, but we can see that I don't get access to any of them.

Is this expected behavior? How can I get access to these functions from inside my "TestMod.jl" module?

Thanks
