Manual RF key in Broadlink MQTT Bridge?

Is there anyway to set RF key manually in Broadlink MQTT Bridge?
I am trying to control a simple RF Sesoo wall switch through Broadlink. It is working just fine if I use some external RF remote for MQTT Bridge to learn the signal and then having the wall switch to learn the same signal.
However, I would like to avoid using external remotes, and I know a good RF generator.
Not sure where do I put the generated key though, is it directly inside the BIN file?

Thanks in advance.

It will depend on that generator

What are the options?

Again. what RF generator are you using?
The manual will tell you where to put that RF code

Right, so you have Broadlink Pro with RF.
Sorry. I am not familiar with the device nor the mqtt bridge
