Ubot registration automation & Review automation.

Does anyone out here know how to build with U-Bot?

I have a bot I'm trying to build but I'm stuck at the registration form as this website uses java to load calendars to select a date, and I can't figure out how to make u-bot work with it.

I have started to build this but can't seem to beat the calendar, can you folks help a fella out?

I'm not sure how ubot works but can you not just fill the text field out with a value? like: 01/27/2019 instead of loading the calender and selecting a value?
