My game is, at least by now, more focused on Sansung. I believe that for iOS the code would be different.
My game has a lot of phone based stories, so I wanted to create real notifications for the person's phone.
It's also based on real days/months.
I wanted to create a label of a phone chat. And then create a notification for a person to receive on their real phone.
For example, a Christmas message. And then estabilish on the code that the person would receive the notification on real Christmas day at 8PM.
The notification would appear on their phone like (something like this):

Or it could be something simpler, like just a "You have a new message" (maybe it's even better since it's simple):

And when they click the notification it redirects them to the game/label of the chat.
I've seen something like this for Renpy once in a game, but I don't really know how to do it.
Does anyone have any idea?
Thank you so much.
