Unable to make android notifications appear as a banner

[sanaddfffrnt]

Hello,
I'm working on displaying Android notifications as banners/bubbles instead of just in the notification drawer. I attempted to set the android_channel_id in our REST API to the OneSignal dashboard's Channel Id value, but it caused issues with notifications appearing in the drawer.

Drawer:

Banner/bubble:

Could someone please provide a clear example of how to configure this in the REST API? The documentation isn't providing enough clarity.

Here is the sendPushNotification function

const axios = require('axios');

const sendPushNotification = async (messages) => {
  for (let i = 0; i < messages.length; i++) {
    const message = messages[i];
    const options = {
      method: 'POST',
      url: 'https://onesignal.com/api/v1/notifications',
      headers: {
        accept: 'application/json',
        Authorization: 'Basic ' + process.env.ONESIGNAL_API,
        'content-type': 'application/json',
      },
      data: {
        app_id: '1234',
        android_channel_id: '1234',
        include_external_user_ids: [message.to],
        contents: {
          en: message.body,
        },
        headings: {
          en: message.title,
        },
      },
    };

    await axios.request(options);
  }
  try {
  } catch (error) {
    console.error('Error sending push notification:', error);
  }
};

module.exports = { sendPushNotification };
