How can I add push notification for mt5 ea

Hey, I understand that I can assign a custom action, but what would I type for it to send a push notification to the mt5 app on my phone.

I already tried

SendNotification(“Notification text”);

but to no avail.

Maybe the action is different for mt5 than it is for mt4

Could anyone offer their expertise?  Thank you
