Getting Bad Credentials while testing in GH Enterprise Server 3.6

[maheshsmartcow]

I am trying to run this action in self-hosted GH Enterprise server (3.6) environment, but I am getting below error

RequestError [HttpError]: Bad credentials
    at /home/nvidia/Projects/actions-runner/_work/_actions/andymckay/labeler/1.0.4/node_modules/@octokit/request/dist-node/index.js:66:23
    at processTicksAndRejections (internal/process/task_queues.js:9[7](https://smartcow.dev/TestOrg/test-repo/runs/4761?check_suite_focus=true#step:2:8):5)
    at async label (/home/nvidia/Projects/actions-runner/_work/_actions/andymckay/labeler/1.0.4/label.js:62:33) {
  status: 401,

and I noticed, it is making API call to github.com instead of the hostname of our GH server. Does this action supports my use case ? Please advise.
