Step-3:
Disconnect existing low voltage doorbell chimes wires labelled Front and Trans or F & T, or Front and Common or 1 & 2
Step-4:
Join existing doorbell low voltage Trans + Front labelled wires together and secure using a marrette or wire-nut or electrical tape.

Close the existing doorbell chime cover.
Now connect dbell to your existing doorbell wires, it should power up and greet/welcome you.
If the blue light on dbell doesn’t turn on, you may have a defective doorbell transformer.
If dbell powers up using supplied adapter or from Android or iOS adapter but not from existing doorbell power, then existing doorbell transformer is defective. You may consider replacing old defective doorbell transformer or you may consult an electrician.
