Who is the owner of Alipay Hong Kong?

Could you please clarify who exactly holds the ownership of Alipay Hong Kong? Is it a subsidiary of the Alibaba Group, or is there a separate entity that manages its operations in Hong Kong? I'm interested in understanding the corporate structure and ownership hierarchy behind this popular digital payment platform in the region. Additionally, are there any changes in ownership or management that have occurred recently, or are there any plans for future changes that investors should be aware of?
