Mechanical chime with ring 2

Hi,Just moved in to a newly renovated house.Hardwired the ring 2 to a transformer that works great and connected seamlessly to my wifi system.Now i need to connect a simple mechanical chime and got stuck.I have the mechanical chime itself but the doorbell has 2 wires that connect to the transformer and that's it.How do i connect it to my ring 2 so that it activates a simple ding dong mechanical ring when pressed? Thank you for your help!Meit
