Trunk opening randomly

[2023 CC hybrid] Does anyone have an issue with the trunk opening randomly? I have a dead battery again (second time) because the trunk decided to open at random. Keys were put away, car locked. Then I get a notification saying that the trunk was open. The first time it happened, I turned off the function (I have an electric trunk) and for some time I was manually opening/closing. But in some point I turned it back k on and it was working normally. (This was months ago now). But recently the button on the trunk stopped working, and I could open either from the key fob or the button inside, so it was more or less ok. However, now it started opening randomly again.. So it is opening all the way, then the fact that lights are on, kills the battery. Right now I have it hooked up to a booster pack, but no luck so far.
