Help with pre-owned Ring doorbell

I moved to a home with a ring doorbell. How do I take control of this door bell and adjust the settings? It is very loud and wakes up the baby when people ring the doorbell. Also, the previous owners shouldn't be able to access the camera because their wifi service has been replaced by mine, correct?Also, what services does the doorbell come with?I have attached a photo of the doorbell.Thank you,Family2022
