Compile errors with FastLED and R4 WiFi LED Matrix libraries

Official Hardware Classic UNO R4 WiFi

I searched the forum for this specific topic, but didn't find anything where FastLED AND the UNO R4's LED matrix are mentioned. I would like to use both the R4 WiFi's built in LED matrix as well as connecting an external string of WS2812B (or similar) addressable RGB LEDs.
IDE 2.3.3 outputs many lines of errors, such as these:

I'm using FastLED v3.7.8 and the UNO R4 board library v1.2.1. Thanks in advance for any help / guidance.

Try inlcuding Arduino_LED_Matrix.h first and FastLED.h as second.

#include "Arduino_LED_Matrix.h"
#include <FastLED.h>

I think this has to do with ensuring the correct macro and register definitions are established first, allowing Arduino_LED_Matrix to configure any necessary hardware settings before FastLED is initialized, thereby preventing conflicts.

That did it - the verify errors are gone - thanks so much!
