Currently, Bitbucket doesn’t provide a way to require approvals specifically from code owners. The existing merge checks — Minimum approvals and All reviewers approve — apply to all reviewers on the pull request, not just those added via CODEOWNERS.

Have the ability to have a merge check that can enforce approval requirements only for code owners (for example, “at least one approval from the matching code owner group”), independent of other reviewers.
