Touchpad not working legion 5

Hello everyone,

I have a new laptop, a lenovo legion 5, on which I just installed manjaro.

Everything is working so far (when I did the first update the nonfree graphic driver was uninstalled and I had a black screen but I was able to correct it).

However the touchpad is not working, I saw this issue when looking at the laptop before buying it but my hope was that with manjaro it could work.

Do you think I may be able to get it to work ?
