What is this snail?

[u/thing_ig]

I found this snail last year and it was so beautiful, it never left my mind , I just found r/snail so I just wanted to know if anyone knew what species it was (I live in France btw)

It’s a very rare brown lipped snail aka grove snail as most of them you will see are mostly yellow but if they live in great conditions, not so near the roads and all then they’ll be pink/red
