Trailer 13 Pin Connector, No Power To Left Side Lights

[megadoo]

I have a 2019 T6 Caravelle RHD. With 13 pin trailer connector delivered with car from factory.
Now I have missed the left side lights on power out of socket. I have tried to look in the fuse chart but can’t find any designated fuse.
Any ideas?

The towing fuses are under the passenger seat.
