VW T6.1 Transporter windows creaking noise

[Neil12]

I've had my T6.1 van kombi for the 6 months and I'm getting a what I can only describe as creaking/clicking noise from my side rear windows when I'm driving around town, it's coming from both sides around the sliding windows area?

Anyone got any ideas?

Picture attached is my side rear windows
