More millenial I think. Maybe even Gen-X, I don't know exactly how old Birdy Nam Nam is. Vid came out 9 years ago. Almost a full generation. I'd definitely associate all the 00s-10s French Electro more with millenial or Gen X. I'd probably say the original French House wave(Daft Punk, Cassius, Oizo) with Gen X and the revival with Millenials. Zoomers aren't into French electronic music so much I think.
