I would like to automatically create a merge request approval rule.
Unfortunately, I don't find an option to specify which branch this applies to.
Using this code always leads to a rule applying to all branches

project.approvalrules.create(
            {
                "name": rule_name,
                "approvals_required": 1,
                "rule_type": "regular",
                "branches": ["main"], # This does not have an effect.
                "group_ids": approver_group_ids,
            })

Any idea how to fix this?

I found a solution

project = gl.projects.get("my-project")
main_branch = project.protectedbranches.get("main")
project.approvalrules.create(
                {
                    "name": rule_name,
                    "approvals_required": 1,
                    "rule_type": "regular",
                    "protected_branch_ids": [main_branch_id.id],
                    "group_ids": approver_group_ids,
                }
            )

I'm not sure if this is even supported by the GitLab API: https://archives.docs.gitlab.com/17.11/api/merge_request_approvals/#create-project-approval-rule
