How can we download the Contact Sensor (1st gen) History event logs?

Hello, I have set up the Ring Base, Contact Sensor, and Range extender as per the Ring setup Guideline. Currently, the Contact Sensor device gives me an Opened/Closed event to the Ring mobile Application. Now, I've one query related to the History event logs. I've two queries related to the topic. 1) If I want to take data of the History event logs like in the form of the file. Then how can we download/collect the history data? Is there any download option available from the web/mobile application? also, tell me the use case of USB who provide in Ring Base Device. 2) How much history event data will be store from web/mobile application ? Is there any internal data memory storage device available? Thank you. Regards, Pratik J Panchal.
