Need help with my wix website code/corvid

Hi all, I already made a large part of my website. But now I’m stuck with making a custom booking calendar. I already have the booking form custom made, I only need help with the calendar part. Functionalities: - choose date and time (Can only piked once) using a custom calendar(The calendar is in the attached image) - web owner and client receive a confirmation mail (confirmation mail contains the date and time AND the booking form information) - the booking needs to be automatically entered in my google agenda - optional different time slots when more products are chosen
