How to use "microk8s kubectl" within a "skaffold.yaml" file?

Question

I have a skaffold.yamlfile like below:

apiVersion: skaffold/v2alpha3
kind: Config
deploy:
  mk:
    manifests:
      - ./infra/k8s/*
build:
  local:
    push: false
  artifacts:
    - image: learnertester/auth
      context: auth
      docker:
        dockerfile: Dockerfile
      sync:
        manual:
          - src: 'src/**/*.ts'
            dest: .
    - image: learnertester/ticketing-client

Now, I have installed microk8s on Ubuntu 22.04 and want to use it. I have also defined an alias mk for microk8s kubectl. But when I change the following line:

deploy:
  kubectl:

To:

deploy:
  mk:

I get the below error running skaffold dev:

parsing skaffold config: error parsing skaffold configuration file: unable to parse config: yaml: unmarshal errors:
  line 55: field mk not found in type v2alpha3.DeployConfig

How should I fix that?
