WLED ESP32 RF433 Questions

Hello, I have been using the WLED ESP32 Music Addressable LED Strip Controller in quite a few projects with great result. Recently I purchased a few of the WLED ESP32 RF433 Music Addressable LED Strip Controllers with intention to leverage the RF433 Switch functionality.

I am looking for some guidance on how to properly wire two WS2812B strips directly into the WLED ESP32 RF433 Music Addressable LED Strip Controller which indicates 2 channel support "2 Channels (Use CLK as second Channel)"

The standard model WLED ESP32 Music Addressable LED Strip Controller clearly has two seperate channels allowing for proper seperation of the strips when wiring to the controller. With the the ESP32 RF333 model we have the Sensor block and Strip block of inputs. It's not clear to me how to wire the 2nd LED strip into this configuration. Which of the 3 cables would be wired into the CLK input and what about the other two cables? Do they share the inputs from strip one or do you leverage inputs from the sensor block or possibly the GND and VCC on the left?

Regarding the RFF functionality. I am guessing this is baked into the firmware that ships with these which clearly is outdated and missing any of the new features and stability since this was compiled. I am looking for some guidance here. It sounds like if I wanted to upgrade to the latest firmware which I always do the RFF switch functionality will be missing as this is a custom module released by Athom. I would then have to compile my own firmware incorporating the code from Athom into the firmware I intended to use. Assuming this is all accurate is anyone aware of any of the latest firmware's, forks that possibly already incorporate the functionality to support the RFF switch not needing to do all the compiling stuff?

For firmware on both configurations I have been using the latest moonmodule release Which includes a variety of enhancements for the microphone.

Thank you.
