Officially published by ESA on October 1st, the raw image (2021-09-30) is already available at Google-Earth-Engine , where you can manipulate with a simple code  filters and thresholds for edge detection. In this demo we used a true color background shifted to reds, and a Normalized-Difference (B4 red, B11 SWIR 1) index for the lava flow. Check the code here .
