How group climate entity with other stuff (input boolean, for example)

Hi to all,
I would group climate component with 2 input boolean, but climate remains alone itself. How can I get my scope?

This is my groups.yaml

riscaldamento:
  name: Riscaldamento
  control: hidden
  entities:
    - climate.riscaldamento
    - input_boolean.poweron_bypass_riscaldamento
    - input_boolean.poweroff_bypass_riscaldamento

But I got only the two inputs grouped together…

Thank you to all!

Thank you. So, without installing third party, is it impossible?

Yes, that is correct.
