BETA questions Promote your event online

As a current user of Constant Contact, I am reading everything I can find on the beta version that will go into affect in 2024. No where can I find information on: 1. How to link live events scheduled through Constant Contact ON A LIVE CALENDAR that customers may visit and use for their purchases. The current legacy version of Constant Contact has this and we rely heavily on our live calendar of events. I see no options in the 2024 beta events we’ve drafted to add events to alive calendar. 2. Once a beta event is created I’m asked to select from the drop-down list where subscribers information will be captured. It does NOT IMPORT MY CURRENT LIST of subscribers as an option. How and when will my current subscribers be forwarded to beta event list?
