Are snapshots supposed to be generated locally or are they supposed to be generated by CI?

We use https://playwright.dev/docs/test-snapshots testing as part of our automated tests. We are debating as a team whether snapshots should be generated locally and committed or if they should be generated as part of CI/CD. I would like to hear from others as to how you are doing it and what pros/cons have you weighted?

For avoidance of confusion, we are debating between:

Option A:

1. generating locally
2. committing
3. CI is responsible for validating that the committed snapshots match the execution of the CI results

Option B:

1. adding a CI action that generates snapshots and adds a commit to the PR
2. engineer is responsible for reviewing the generated snapshot
3. CI is responsible for validating that the committed snapshots match the execution of the CI results
