Does CompatHelper send PRs to update project.toml files in subdirectories?

https://github.com/JuliaRegistries/CompatHelper.jl/issues/294 suggests that it does, but I hadn't received any PRs to update my [docs/Project.toml](https://github.com/vtjeng/MIPVerify.jl/blob/485599386651ad446f32f5598bf7e0318d8ec377/docs/Project.toml#L6) for a while (the most updated version of `Documentation` at the time of writing is `0.27`). Is this because

- My github actions [configuration file is](https://github.com/vtjeng/MIPVerify.jl/blob/485599386651ad446f32f5598bf7e0318d8ec377/.github/workflows/CompatHelper.yml) misconfigured
- Specifying a version of `~0.23` with the tiled causes CompatHelper to skip trying to add dependencies?

FWIW, I have received [many](https://github.com/vtjeng/MIPVerify.jl/pulls?q=is%3Apr+%22CompatHelper%3A+bump%22) PRs from CompatHelper for my main `Project.toml` (just not for `docs`).
