I got a 30-day Ring Protect Plus Trial, what happens when it expires?

Hello neighbors! We had our Ring Video Doorbell replaced recently, but it also came with a 30-day Protect Plus trial, we have Protect Basic before we got the trial. What happens when the 30-day trial expires, would it go back to Protect Basic or it would continue with Protect Plus? I wouldn't want to pay extra so I want it to go back to the Basic plan. Any bit of help would be greatly appreciated. Thank you very much!
