When using "Advanced debloat", applications were not displayed.
So I did a clean install + NoBloatware and all apps + Samsung apps are present, very good job.
At first, I thought that the "NoBloatware" option was an installation without an application, but on the contrary, everything is available (finder also works)
For now, everything works: Sidebar, screen sharing with TV, SIM, call blocking, Samsung app. I am very satisfied.
Installed on Samsung Galaxy S9 French version + SFR - Last TWRP version.
