Ender 3 V2 screen version 3 firmware

what folder does the firmware go in for ender 3v2 gen 3 screen (WM32SRET5-50). I have tried so many folders, multiple small sd cards formatted on linux and it still can’t find it

I found another forum post for the gen3 screen and it had to files FlashBin and
Firmware.bin that go in the root, this from rerap for v3 firmware ,there is a nice bundle there that works with example, will this marlin forum offer the same for screen? Marlin 2.1.x on Ender-3 V2. Can't Update Screen Firmware
