Dashcam installation (Stringer cabling)

Has anyone already hung a Dashcam in his Stinger? I am currently thinking of having one installed, but still puzzled about the connection possibilities. I want to have the Dashcam very discreet, i.e. the cable should be laid as invisible as possible. Unfortunately, I believe that this does not work with connection to the front cigarette lighter, especially since the flap can then no longer be closed. Another possibility would be possibly the rear 12V connection. it might be a connection on top of the roof lighting, but there might be warranty problems later, as a third party user was connected to the power grid. How did you solve this? PS: Please don’t have a legal discussion. The topic is still a grey area, even after the last case law.
