A JS snippet you can run on the Digital Ocean notification page to read all notifications. Start it off by running the start_processing() function

script.js

var interval;

function start_processing(){
	interval = setInterval( open_notifications, 1000 );
}

function open_notifications(){
	let notifications = document.querySelectorAll('.notification-listing .notification-row:not(.acknowledged) .action');

	if( !notifications.length ) {
		clearInterval( interval );
		console.log('Done with this page');
		go_to_next_page();
		return;
	}

	console.log('click');
	notifications[0].click();
}

function go_to_next_page(){
	let pagination = document.querySelector('.notification-listing + .Pagination');
	let next_page = pagination.querySelector('.is-active + .page');

	if( !next_page ) {
		console.log( 'All done!' );
	}

	console.log( 'Going to the next page' );

	next_page.click();
	setTimeout( start_processing, 2000 )
}
