Xfinity Chime Box Question- Voltage

Hello,

I have an xfinity doorbell and I was not able to wire it to my existing doorbell due ti it being an old school one.   It only supplies like 11volts and would not be sufficient.   So, I purchased an adapter and ran a wire to an outlet... Works fine/  No issues.  Now, the issue I AM having is the chime.  Since I was not able to use my existing setup,  I do not have a chime.   Anyone have this issue?  Is there a way to have a chime set up so I can hear it in the house without being married to my phone?  I like the doorbell since it records 24/7 and connects to 5Gh wifi.   I just need a chime of some sort.  An external chime would definitely be nice, such as the Chime devices ring provides
