I want to run a pre-push hook even if there are no changes to the root directory

[ghost]

pre-push:
commands:
run-tests:
root: "./my-app"
run: "npm run test:unit"

I want to run that script even if there are no changes to the root directory.
Now im getting
╭─────────────────────────────────────╮
│ 🥊 lefthook v1.10.1 hook: pre-push │
╰─────────────────────────────────────╯
sync hooks: ✔️ (commit-msg, pre-push)
│ run-tests (skip) no matching push files

────────────────────────────────────
summary: (done in 0.01 seconds)

How can I force this similarly to when I run npx lefthook run pre-push --force ?
