SP530e bin files for flash

Apologies if this is a stupid question, but I can’t find boot-loader or partition files foe SP530e flash anywhere.
I was able to find main image IE WLED_0.15.0-b3_ESP32C3_4MB.bin but the guide indicates C3_bootloader.bin and C3_partitions_4M.bin also required.
Possible I have misunderstood entirely? Is anyone able to clarify
