1 . yes we made it for minimum load on server . But to send the push notifications , we are using curl library of php .We used curl because there was only one way to send notification
and it was to make a hit to google firebase server using POST of curl . We could use the post method using javascript post from browser (no load on server) but then your Push notification server key will be exposed and this is a possible security loophole .Therefore we used curl method , there is a single curl command used for this ,so I dont think there will be much load on server due to this .
Secondly we have made it based on buddypress notifications system , so user can keep track of the one to one notifications that are related to course and his activities on the site and for instructors activities on site .
2 . There is no need to purchase the chat plugin .You can purchase push notifications individually .
3 . Yes .
4 . Integration of push notification is under development for wplms mobile app .
5 . Yes if they use a browser that supports push notifications and has allowed permissions to send notifications for your site .
