How to: use a logical `and` to evaluate a conditional expression in a Config template

How do I display a Config option only when two or more other items are True or False? I tried

when:  repl{{ ConfigOptionEquals "option_one" "0" }} & repl{{ ConfigOptionEquals "option_two" "0" }}

but this isn’t working as expected.

Answer:
Only show option foo if both options are false.

    - name: conditional_and
      title: Conditional conditional
      description: only shows up when both option_one and option_two are set to False
      when: repl{{  (and (ConfigOptionEquals "option_one" "false") (ConfigOptionEquals "option_two" "false")) }}
      items:
        - name: foo
          title: foo
          type: text
          default: "foo"
