My existing old doorbell position is facing sideway, 90 degree from the entry path which Ring doorbell should face towards

Hi, I am looking for help to get ring doorbell installed so that it can work as expected. My existing old doorbell position is facing sideway, which is 90 degree from the entry path where the Ring doorbell should face towards and monitor with. Which products should I buy to resolve this issue? I actually searched quite a while, there was recommendation for accessory named 'angle adjustment', which can improve by 20-40 degree, but comments /feedback are very bad, also mine needs to be adjusted by 90 degree, so have to pass. Another recommendation is to get wifi ring doorbell without connecting to the old existing doorbell, but which model works better? I need a basic ring doorbell to monitor any strangers behaviors in front of my doorway, and that's it. Thanks.
