How to get a list of all Azure DevOps project users using REST API with TypeScript

I am developing an Azure extension. I found this documentation for the Azure REST API. I wonder if there is any way to list the users in a project; something like:

export async function getAllProjectMembers(): Promise< foo > {
  const projectId = await getCurrentProjectId();
  const teamMembers  = await getClient(GraphRestClient).listUsers(projectId);
...
  return membersInfo;
}

Of course, listUsers() doesn’t actually exist, unfortunately.

I haven’t found anything in MS repo for Azure API for that.

Is there any way to do that? Maybe I missed something in the repo? If not, how can I code the HTTP request in TypeScript?
