Pass-through, mapping, mixing RC9&10 to output 5&6

hi, trying to find an easy way to configure my Pixracer motor outputs to be mapped with my RC9 and RC10. I’ve seem so many topics about this, but no real simple solution. Editing mixers files I do not know how, I’ve find some functions like RC_MAP_AUX1 but unable to use it. My goal is just to be able to pan and tilt my storm32 gimbal using mavlink. Any kind of help is welcome!

Ok, it appears that the command RC5_FUNCTION was replaced by SERVO5_FUNCTION, so I was able to tilt using SERVO5_FUNCTION 59. For SERVO6_FUNCTION 60, so this works for Pan Tilt from RC9 and RC10, hope it will help someone.
