Which fuse to use on a 2023 Superb for a dashcam hardwire installation with a fuse splitter?

Just bought a six months old Superb DSG Diesel Estate. In the past, I just used the 12v socket for my dashcam in my old Superb Estate II. I had to unplug it every time I turned the engine off so as not to drain the battery.  With the new Superb, I would like to hard wire the dash cam in with a fuse splitter. I am just wondering which is the best fuse to use in the fuse box which would allows the dash cam to turn off when the engine is off?  Any advice from someone who has done it would be much appreciated. Many Thanks.
