Private events, by invitation

Hello,

I am making a site for individual and private events.

Needed:

– Private events, by invitation
– Exclusive access to the event
– Have an exclusive guest list for the event
– The guest must confirm their attendance (mandatory and optional)
– The event must be hidden after it takes place
– The events are not paid, they are by invitation
– Invitations will be made through sendinblue, by email
– The event owner must have the power to update all the information of their event. Must be done from FrontEnd

Can I try your version for free and then buy the pro?

Thank you,
