Work with Issue Template

Here is a proposal issue template: .github/ISSUE_TEMPLATE/3_proposal.yml

name: Proposal
description: Suggest an idea for this project
title: ''
labels: proposal
assignees: peaceiris
body:
  ...

Scenario:

When a user opens an issue with the proposal template, the proposal label will be added automatically.
This action can detect that labeled event and create a template comment of proposal.

Work with Other Auto Label Actions

Authenticating with the GITHUB_TOKEN - GitHub Docs

When you use the repository's GITHUB_TOKEN to perform tasks, events triggered by the GITHUB_TOKEN, with the exception of workflow_dispatch and repository_dispatch, will not create a new workflow run. This prevents you from accidentally creating recursive workflow runs. For example, if a workflow run pushes code using the repository's GITHUB_TOKEN, a new workflow will not run even when the repository contains a workflow configured to run when push events occur.

You need to provide a personal access token (with public_repo for a public repository, repo for a private repository) to an auto label GitHub Actions or GitHub Bot like actions/labeler.
