    Metadata details:

    the code of the file until where you have to start completion: # frozen_string_literal: true

class GroupActionLogger
  def initialize(acting_user, group)
    @acting_user = acting_user
    @group = group
  end

  def log_make_user_group_owner(target_user)
    Grou
    
  def log_add_user_to_group(target_user, subject = nil)
    GroupHistory.create!(
      default_params.merge(
        action: GroupHistory.actions[:add_user_to_group],
        target_user: target_user,
        subject: subject,
