Device Speaker Volume adjustment on Ring doorbell

HelloI got my first Ring doorbell ( 2nd gen). It is installed in an apartment building. The speaker is so loud that i am sure it disturbs people in the building. Had two chats with CS. Both insist i should have “Device Speaker” volume slider in the app under Device - General Settings - Volume settings. But i only have Doorbell Sounds slider there. Seems a UI element is missing in my app ? Did anyone encounter that please ? What should i do to solve ? My app is on iOSThanks
