How to use the @lhci/utils/src/build-context.js.getCurrentBranch function in @lhci/utils

async function runLHCITarget(options) {
  if (!options.token) throw new Error('Must provide token for LHCI target');

  const api = new ApiClient({rootURL: options.serverBaseUrl, extraHeaders: options.extraHeaders});

  const project = await api.findProjectByToken(options.token);
  if (!project) {
    throw new Error('Could not find active project with provided token');
  }

  const hash = getCurrentHash();
  const branch = getCurrentBranch();
  const ancestorHash =
    branch === 'master' ? getAncestorHashForMaster() : getAncestorHashForBranch();

  const build = await api.createBuild({
    projectId: project.id,
    lifecycle: 'unsealed',
    hash,
    branch,
    ancestorHash,
    commitMessage: getCommitMessage(hash),
    author: getAuthor(hash),
    avatarUrl: getAvatarUrl(hash),
    externalBuildUrl: getExternalBuildUrl(),
    runAt: new Date().toISOString(),
    committedAt: getCommitTime(hash),
    ancestorCommittedAt: ancestorHash ? getCommitTime(ancestorHash) : undefined,

test: async ({serverBaseUrl = '', token = ''}) => {
      const client = new ApiClient({rootURL: serverBaseUrl});
      const project = await client.findProjectByToken(token);
      if (!project) return true;
      const builds = await client.getBuilds(project.id, {
        branch: getCurrentBranch(),
        hash: getCurrentHash(),
      });
      return builds.length === 0;
    },
  },
