Confused

2009 Dodge Journey lift gate access opening to open lift gate is not working. Can the panel on the outside that the license plate mounts to be removed by the four screws at the top of that panel be removed to get access to the latch

My Dodge Journey lift gate won't open I tried spraying penetrating oil through small rectangle access opening and under lift gate from the inside and each side of the handle from the outside and then tried turning white plastic (+) (- -) option through the access opening under the lift gate interior light and it didn't work is there any other suggestions. Would going in through over the license plate from the outside be another option?
