Getting usage of channel point

Chat and IRC

When I try to do this, I got an error :

  let getRewards = new XMLHttpRequest();

  getRewards.open("GET", `https://api.twitch.tv/helix/channel_points/custom_rewards?broadcaster_id=${broadcaster_id}`, true);
  getRewards.setRequestHeader('Client-ID', `myid`);
  getRewards.setRequestHeader('Authorization', `Bearer myoauth`)
  getRewards.send();
  
  getRewards.addEventListener('load', function() {
    const rewards = JSON.parse(getRewards.response);
    console.log(rewards)
  })

{
error: ‘Unauthorized’,
status: 401,
message: ‘Missing User OAUTH Token’
}

{
  error: 'Unauthorized',
  status: 401,
  message: 'Missing User OAUTH Token'
}

I just refreshed my OAuth, and it still doesn’t work
