Insert Calendar API google via REST Delphi Response 401

Question

I am trying to use the REST components to make an HTTP request with the method POST to insert a calendar into the API, but my request is returning error "401 - Not authorized".

I’m trying to include the token in the request, but I don’t know if I’m doing it right. How can I fix this?

My current code

procedure TOAuth2TesterFrm.incluir_btnClick(Sender: TObject);
var
json,outro_json,token: String;
begin
token:=AccessTokenEdt.Text;
json:=(
'{"kind": "calendar#calendarListEntry", "etag": "0", "id": "[email protected]", ' +
'"summary": "Calendario Outro", "description": "Descrição do evento", '   +
'{"date": "2020 August 11", "dateTime": "2020-08-11T17:35:36+03:00"}'+
'"timeZone": "Brasília-DF", "colorId": "15", "backgroundColor": "#9fc6e7", "foregroundColor": "#000000", ' +
'"selected": true, "accessRole": "owner", "primary": true, '+
 '"defaultReminders": [{"method": "popup", "minutes": 30}, {"method": "email", "minutes": 10}], '  +
'"notificationSettings": {"notifications": [{"method": "email", "type": "eventCreation"}, ' +
'{"method": "email", "type": "eventChange"}, {"method": "email", "type": "eventCancellation"}, ' +
'{"method": "email", "type": "eventResponse"}]}}');
outro_json:='{"summary": "Batata"}';
try
    client.ResetToDefaults;
    request.ResetToDefaults;
    response.ResetToDefaults;

    client.BaseURL:='https://www.googleapis.com/calendar/v3/';
    response.ContentType := 'application/json';
    request.Method := TRESTRequestMethod.rmPOST;
    request.Body.ClearBody;
    request.AddBody(outro_json);
    client.AcceptEncoding:='utf-8';
    client.ContentType:='application/json';
    request.Resource := 'calendars';
    request.Params.AddHeader('Authorization','Bearer '+token);
    request.Params.ParameterByName('Authorization').Options := [poDoNotEncode];


    request.Execute;
    ShowMessage(request.Response.StatusCode.ToString);
finally
  request.Free;
      response.Free;
      client.Free;

end;
  end;
