Innr 4m Ledstrip with direct driver: anyone have experience in splitting the strip?

Hi, I’m trying to find a good ledstrip solution for a few bookcase lights. Right now I’m looking at a 4m Innr strip with a direct power connection (no plug), but I’d need to cut the strip into 4 pieces, and link the pieces with some wire. Has anyone done this, that could tell me if it’s possible, and preferably how long the wire connections can be?

Below is a quick sketch of the situation. (red are strips, green are wires)

would this situation (strips and wires in total are ±15m) be possible with just the one zigbee driver that comes with the ledstrip?

edit: just realized the driver doesn’t need a return, so made a new image
