Getting the environment of a function within a function?

So lets say I have a modulescript and I want to iterate through every variable I declared within module.new() from module.new()

what argument to getfenv() would you use?

For example, this is a modulescript in workspace

local module = {}
function module.new()
    local asdf = "ASDF"
    local num = 1
    local char = 'a'
    for _, v in pairs(getfenv()) do
        print(v);
    end
end
module.__index = module
return module

and this is another script in workspace

local test = require(script.Parent.ModuleScript)

test.new()

Yet when it runs, it only prints the name of the ModuleScript
