I have a remote control for a video light, it's called 'Godox RC-A5'. The most detailed documentation I could find for it is here https://fccid.io/2ABYNRC-A5/Test-Report/Test-Report-2708894.pdf. The remote has 16 'channels' you can choose between and claims to operate in the 433.92MHz band.
I have an Arduino Uno with an RF receiver (https://components101.com/433-mhz-rf-receiver-module) and transmitter (https://components101.com/433-mhz-rf-transmitter-module). The documentation I linked to in the previous paragraph says that the remote control uses ASK modulation, so I tried using this but it didn't detect anything.
When I log raw input values from the receiver, I can tell it definitely goes high when I press a button on the remote control.
Is there any way in which I can look at the radio being sent from the remote control and decode it so that I can then replicate the signal and send it from my transmitter?

I actually just finished an arduino library for this exact thing, although only the first 2 channels work so far. Try this, see if it works (assuming you still need it) https://github.com/BrittonPlewes/GodoxRemote
You for sure can see the signal on a scope, but I had to make my own version of SimpleRcScanner to capture and analyze the signal.
