How do I setup id when creating new users?

databaseHooks: {
  user: {
    create: {
      before: async (user, context) => {
        // Generate user ID from email
        console.log("User before creation:", user);
        
                
        if (user.email) {
          const customId = generateUserId(user.email);
          
          return { 
            data: { 
              ...user, 
              id: customId
            },
            forceAllowId: true // This is required to allow custom IDs
          };
        }
        
        // If no email is available, let BetterAuth generate the ID
        return { data: user };
      },
      after: async (user) => {
        // Perform actions after user creation
        console.log("User after creation:", user);
      }
    },
