  spec:
    approvers:
    - input: reject                            👉🏻    # one of: approve, reject
      name: bar
    - input: pending
      name: tekton
    - input: approve
      name: baz
    numberOfApprovalsRequired: 2
  status:
    approvers:
    - bar
    - tekton
    - baz
    approversResponse:
    - name: baz
      response: approved
    - name: bar
      response: rejected
    state: rejected                         👉🏻   # one of: approved, pending, rejected

• User will have to patch the input field for his username

• Sceanrios Handled
  • Until and unless approval task does not get approval from all the users as true, till that approvalState will be pending
  • If any one user rejects the approval task we will mark the approvalState as rejected and then the pipelinerun will fail
  • If a user approves for the first time and still approvalsRequired limit is not reached i.e. approvalState is in pending state then user can still change his input and mark the approval task as reject
