Trying to extend connection to a Winstar OLED Tab (Flat) Diaplay

Hello there,
I would like to buy a flat/flex ribbon wire in order to extend the distance between my Arduino and this lovely Winstar display. I asked the manufacturer (no answer unfortunately) and the shop, but they couldn't point me towards a any flat connection.
So far I always ever worked with classic OLED displays but would love to replace them with these flat ones.

Any idea of what I could use?

Many thanks for your help!
