If you use CurrentUnitOfWork, you can catch the exception also and using UserFriendlyException you can throw the desired exception. UserFriendlyException is a specific type of exception so ABP directly shows exception message to the end user.

Example:

try
{
    await _repository.InsertAsync(...);
    await CurrentUnitOfWork.SaveChangesAsync();
}
catch(Exception ex)
{
    throw new UserFriendlyException("user friendly exception message");
}
