1. EV3-G (the EV3 software) + MBC custom block
The closest to blocks: import the MBC custom block once, then read the colour code and vividness of all 12 spots. EV3-G tutorial
EV3 Classroom blocks only know LEGO's own sensors. On the EV3, the SharpShot Vision WRO edition reports device type 95 (HUE12 mode), which is not a stock LEGO sensor, and Classroom cannot import custom blocks. So it cannot read this camera. Use one of the three ways below instead.

Boot the EV3 from a Pybricks microSD card and read every value in Python. Pybricks tutorial
No new microSD card: read the raw data with a clev3r BASIC program. clev3r tutorial
You can set 12 spots (S1 to S12) on the camera picture. Each spot has a colour code (0 to 239 colour: red 0 / 239, yellow 40, green 80, cyan 120, blue 160, purple 200; 240 to 245 white, 246 to 250 black; 255 = spot not enabled) and a vividness (0 to 255).
Complete examples are on the SharpShot Vision WRO edition EV3 examples page.
