Merge Request Approvals - Release Controls (HD)

You can configure your merge requests so that they must be approved before they can be merged.
You can create required rules about the number and type of approvers before work can merge. In addition, you can specify a list of users who act as code owners for specific files, and require their approval before work can merge.
You can configure merge request approvals on a per-project basis, and some approvals can be configured on the group level.

Can we set approvers in a group?, I don't want to do just in a project level.

How to send email notifications to the set approvers to let them know that merge request is awaiting their approval?
