Ways to program ALLMATIC AKMY2 26995MHz remote control

Hi mates !

Sorry, I'm a beginner !
Well, I just bought a new remote control for my automated gate, an ALLMATIC AKMY2 26995MHz remote control for those who know. By reading the programming instructions, I see that I need a remote control already programmed on the automation. And yet, I don't have one. So, is there another way to do this programming for my new remote ?

Thank you for your help !
