How to connect Eufy doorbell 2k to Honeywell DW915

How do I connect the eufy doorbell 2k to my existing Honeywell dw915 chime without having to put batteries in the Honeywell dw915 and that I am also always charging the batteries of the eufy doorbell. I have an 8 to 24 v transformer connected to the 8v.
The transformer is now connected to AC1 and AC2, and the old push button to A1 and A2 of the Honeywell. I hope someone can draw a connection diagram for it
