Documenting termux-notification-list

I wrote this basic documentation (which I was unable to add to the locked wiki).
A new page needs making and linking to from https://wiki.termux.com/wiki/Termux:API

Here is what I wrote:

termux-notification-list

The termux-notification-list API command lists Android system notifications from other apps in the format of a JSON list of notification objects. For example, this might be useful to make a a script that detects when a particular notification is received, e.g: after a reminder app has a reminder notification, a script could do some custom action like turning on the torch by polling this command.

Usage

termux-notification-list
The output of the command is like this:

[
    {
        "id": -100,
        "tag": "",
        "key": "0|com.example_organisation.app_name|-100|null|10151",
        "group": "APP_NAME_ONGOING_NOTIFICATION",
        "packageName": "com.example_organisation.app_name",
        "title": "Notification title",
        "content": "Notification content",
        "when": "292269055-12-02 16:47:04",
        "lines": [
        "Text from the notification"
        ]                                                               
    },
    {
        "id": -100,
        "tag": "",
        "key": "0|com.example_organisation.app_name|-100|null|10151",
        "group": "APP_NAME_ONGOING_NOTIFICATION",
        "packageName": "com.example_organisation.app_name",

        "lines": [

        ]                                                               
    }

On some Android versions, allowing permission to notifications can be tricky. Please add more detailed steps here that worked for you.
