Banner not showing on local notifications

Local notification does not display banner when called on android, Only vibrates and adds to the notification centre. (The default priority for android).

How to escalate the priority of the local notification?

I can see from the Aurora docs that it is possible
"
JPushInterface.EXTRA_NOTI_PRIORITY
Support SDK 3.0.0 or later，and support rom 16 or more.
When the default is 0 and the range is -2 to 2 , other values will be ignored and defaulted.
Notification priority
Bundle bundle = intent.getExtras();
String prio = bundle.getString(JPushInterface.EXTRA_NOTI_PRIORITY);
https://docs.jiguang.cn/en/jpush/client/Android/android_api/
"

I have tried to add in the priority into the extra section without success.
JPush.addLocalNotification({
messageID: "123456789",
title: "testMe",
content: "messageValue",
extras: { priority: '2' }
})

Note: I can trigger the banner by enabling floating notifications through settings. But using other libraries I have been able to trigger the local notification banner without making the user modify their settings.

Thanks!

Start at the JPush.addLocalNotification entry point and compare how the React Native plugin passes extras into Android local notifications. Read the linked Android notification-channel and JPush priority documentation first; done means a local notification displays a banner without requiring floating notifications to be enabled in device settings.
