And my high quality version:

WLED firmware
Bootloader
https://github.com/Aircoookie/WLED/releases/download/v0.13.1/esp32_bootloader_v4.bin
WLED Firmware
https://github.com/wled/WLED/releases
Wemos Shield GUI Flash tool
https://github.com/srg74/WLED-wemos-shield/blob/master/resources/Firmware/WLED_%20ESP_Flasher/Windows.zip
Bootloader isn’t necessary.
GUI flash tool works and doesn’t require usage notes. No luck was had with ESPTool.
After flashing, WLED-AP shows as an available SSID to connect to.
