云函数没有权限调用subscribeMessage接口怎么办

       // 发送订阅消息
        await cloud.openapi.subscribeMessage.send({
          touser: user._openid,
          templateId:'模版ID',
          page: 'pages/index/index', // 点击卡片后跳转的页面
          data: {
            date: { value: prediction.nextStart },
            thing: { value: '记得准备好用品，注意休息哦～' }
          }
        });
      } catch (err) {
        console.error('发送失败', err, user._openid);
      }
