How stop workflow when the plan detects no changes

What is the easiest way to find if the "terraform plan" command detect zero changes so I can stop the workflow and don't call "terraform apply"?

With the previous edition this action (hashicorp/terraform-github-actions) I could use a condition like below:

```
- name: 'Terraform Apply'
if: steps.tf_plan.outputs.tf_actions_plan_has_changes == 'true'
id: terraform_apply
uses: hashicorp/terraform-github-actions@master
with:
tf_actions_version: ${{ env.tf_version }}
tf_actions_subcommand: 'apply'
```

How can I do have a similar condition with `hashicorp/setup-terraform` ?
