How to chain axios get requests while response hasMore flag is true

I am hitting an endpoint that gives me a list of users but the result is paginated. The response contains a flag hasMore which tells if there are more users to be retrieved and an offset to make the next api call with.

Right now I am able to make multiple calls by manually checking if the result hasMore is true. How do wrap this logic in a while loop?

function getUsers() {
  let users = [];
  
  axios.get(url)
    .then(res => {
      res.users.forEach(user => {
        users.push(user);
      })
      
      if (res.hasMore) {
        return axios.get(url + '&offset=' + res.offset)
      }
    })
    .then(res => // repeat what I've just done and keep checking hasMore
    // How do I check this in a while?
    
}

can you move the users = [] up a level?

let users = [];

function getUsers(url) {

  axios
    .get(url)
    .then(res => {
      res.users.forEach(user => {
        users.push(user);
      })

      if (res.hasMore) {
        getUsers(url + '&offset=' + res.offset);
      }
    })
    .catch(err => {...});
}
