Codex overrides Github PR Template

I have a PR template defined in .github/pull_request_template.md in my project. I haven’t gotten Codex to successfully use this template when creating a PR. I added some instructions in agents.md and I’ve tried adding it in the general settings as well. But Codex still seems to be creating it’s own description on PRs that it creates. How can I tell it to correctly use the already defined PR template?
