Door Handle Sticking

Just as the car is starting to run good the rear door handle seems to be sticking in the open position, this seems to happen if the car hasnt been used for a day or two.

I’ve looked to see if I can spray some WD40 into the handle but its almost impossible to see anything.
My guess is another dealership visit unless someone has an y ideas ?

Never use WD40 for lubrication, as it’s a rust remover. It only lubricates for a moment. A PTFE spray lubricant will do the trick because there is many plastic parts.

I cant see where to spray it, theres no obvious gaps ?
