Help identifying connector

Hi!

I have bought a Geberit shower toilet/bidet with a motion sensor but it's aimed at the front while the toilet is installed sideways. So I've opened the thing up and I can take out the motion sensor, but the cable it's connected to is too short to do anything with. So I'm looking to buy/make an extension cable, but I have no idea on how to find it. So I took pics of the connector and I'm hoping you can help me find the type of connector (and if someone has a buy link: even better!). Thanks!
