Emulate with Arduino the RF signal emitted by a garage remote control to clone it with a cloning remote

I use a CC1101 module as a receiver with an Arduino Nano. I use another transmitter to send commands to it to control various devices. The idea is to clone the transmitted signal with a cloning remote control to use the replicating remote's buttons.
Thanks

If you have written the code for the 'transmitter' why would you want to clone it since you already know how to make and code a transmitter ?

I have a 4-button remote control. I've cloned one button for the garage door opener and want to use the remaining buttons for other Arduino-controlled devices.

The question is: how to emulate the protocol used by a 433.92 MHz fixed-code garage door remote using any of the Arduino libraries (rc-switch, elechouse, etc.).
Protocol used by remotes such as SOMFY TELIS, TELCOMA FM402, NORTON NEO, etc.
