So there are a few things that I do not like about Linux in general; quite a lot of things do not work automatically. One of the problems I have faced is that my Microsoft Designer mouse won't work with Ubuntu 18.04 LTS. After some research, I found this solution suggested by Newbuntie to work well, so I'm going to post this here for any other people going through the same trouble.
Basically, enter the following commands and you are good to go.
$ sudo add-apt-repository ppa:bluetooth/bluez
$ sudo apt install bluez
Enjoy!
