once your done you can simply load ImgBurn from the shortcut it creates on the desktop, or from within the PlayOnLinux program itself. PlayOnLinux does not need to be running for ImgBurn to work (although you run PlayOnLinux during initial setup/configuration of ImgBurn) as it's easiest to simply load ImgBurn from the desktop icon it creates as at this point it's works just like it does on Windows (as I was recently playing with ImgBurn and overburning a standard audio CD on a CD-RW disc etc and it worked). NOTE: PlayOnLinux is separate from your standard system Wine installation. so even if your using the standard Wine installation (i.e. ; after those six steps are done issue 'sudo apt install wine-desktop-files' which gives you the proper Wine entries on the Mint menu) and something gets out of whack, it won't effect your PlayOnLinux setup with ImgBurn since it's running in it's own what I think is referred to as a 'wine prefix', or 'virtual drive' one could say which people are probably a bit more familiar with that term.
