Razer Connect: Sync w/ Apex

Hi. I play Apex with a Razer Huntsman keyboard, and Apex Legends works with Razer Chroma lightning. In theory, I am supposed to find 'r5apex.exe' in the Razer Connect menu, on Synapse, to link keyboard and game. BUT unfortunately, that isn't the case. I'd like to precise that one year ago, it worked. Since, I reinstalled the game, first on a disk that isn't the main one, then on C:. But it still doesn't work. Any idea to fix this problem? Thanks,
