Additionally,it maybe you need to modify the code in suave-std/src/Suapp.sol to make it inheritable. If this modification is done according to the official documentation tutorial, it will show a "cannot be overridden" error.
modifier confidential() virtual {
require(Suave.isConfidential(), "must be called confidentially");
_;
}
