# Use GitHub App to generate an installation access token to allow PRs created by Backbot to trigger workflows.
# This is necessary because PRs created using the default GITHUB_TOKEN do not trigger workflows plus
# GitHub doesn't allow to alter any file within the .github/workflows directory using the default GITHUB_TOKEN.
# This action will create a token with the permissions defined below and is valid only for 1 hour, but if the
# job completes before that 1 hour limit, the token will automatically be revoked.
