I have an 401 Unauthorized when I try to make a post request. The problem is that it's working using the Graph Explorer but I have this error using the access token given by this method:

let getTokenPopup = request => {
   return myMSALObj.acquireTokenSilent(request).catch(error => {
     return myMSALObj
    .acquireTokenPopup(request)
    .then(tokenResponse => {
      return tokenResponse;
    })
    .catch(error => {
      console.log(error);
    });
})};

This is the scope using to the access token:

export const tokenRequest = {
scopes: ["User.Read","email","profile","openid","Calendars.ReadWrite"]};
