Is it possible to tell beautysh to format to 2 spaces instead of 4?

[Zeioth]

I'm trying this, but it is still formatting to 4 spaces instead of 2.

    --  null ls [code formatting]
    --  https://github.com/jose-elias-alvarez/null-ls.nvim
    {
      "jose-elias-alvarez/null-ls.nvim",
      dependencies = {
        {
          "jay-babu/mason-null-ls.nvim",
          cmd = { "NullLsInstall", "NullLsUninstall" },
          opts = { handlers = {} },
        },
      },
      event = "User BaseFile",
      opts = function()
        local nls = require("null-ls")
        return {
          sources = {
            nls.builtins.formatting.beautysh.with({
              command = 'beautysh',
              args = { 
                "--indent-size 2", 
                "$FILENAME" 
              },
            }),
          },
          on_attach = require("base.utils.lsp").on_attach
        }
      end
    }
  },

Does it work from the command line? If so try separating it into two arguments:

              args = { 
                "--indent-size",
                "2",
                "$FILENAME" 
              },
