Cannot get Freenove 5 inch touch screen to work with Manta M5P DSI+ CM5

So I am currently experiencing confusion when it comes to interfacing a Freenove raspberry pi 5inch touch screen with the Manta M5P + CM5. First of all, I noticed that the DSI at the back of the M5P is a 15 pin 1mm pitch FPC connector rather than a 22 pin that the raspberry pi 5 usually has. This means that if I look for DSI FPC cables for raspberry pi screens (not for the cameras), all that I find are the 15 pin to 22 pin FPC cables. I managed to find a 22 pin to 22 pin ribbon cable (type B reversed - blue stiffners arent on the same side of the cable) which still didnt bring any luck.

I have tried even running the code provided by the manual from BTT:

sudo wget https://datasheets.raspberrypi.com/cmio/dt-blob-disp1-cam1.bin -O /boot/firmware/dt-blob.bin

However no luck. When I power on the manta board the LCD quickly flashes (black backlight turns on for a split second) then turns off. I thought maybe the type A straight through fpc cables may fix this issue however I cannot find any that are specifically mentioned to work with raspberry pi LCDs, although I have found a handful of type A FFC/FPC cables but again, they are pretty generic and not guaranteed to work with LCD/DSI.

Any pointers would be much appreciated

Could you please provide a link to a dsi cable that you got to fit in the connector. Seems like every cable I try is to thick. Looking for a 15 pin to 15 pin that will fit.

Thank you
