Angular material on ionic 6

I would like to use angular material in my ionic 6 capacitor v4 application.
I execute " ng add @angular/material".
All fine, files are updated correctly, but when I use components, the styles are not applied.

I found many tutorial for ionic 5 but nothing on ionic 6 (don’t know if something change)

Someone use angular material on ionic 6?
there’s some tricks?
