Set persistent notification for certain app
The problem: I recieve skype messages while afk and I don't notice the little orange dot in the trayicon when I'm back.
The question: I'd like to make Skype's notifications persistent on screen (until I dismiss them) so that I don't miss them. Is it possible to make notifications sent by apps persistent?
I'm on: Ubuntu 18.04 LTS using Skypeforlinux (Skype version 188.8.131.52)
Any other solution to make me notice skype's notifications (like make blinking dock icon) is welcomed
P.S. it is not a duplicate of older similar question since those refer to a different skype version that didn't used the system notification by default. Now it does and it isn't possible to customize it anymore (I was used to setup a messagebox whenever a message from a new chat was sent)
