Community platform: Letting event creators accept or deny requests to join

Hello Softr experts

I am creating a platform with user-submitted events for other users to see/join.

I have the list detail page with individual events, and a button that currently adds the clicking user to the event attendees, BUT, instead of them being added automatically, I want it to be up to the event creator to decide.

So when they fill in information and click the button, the event creator gets notified and can then accept or deny that request

And lastly, if the event creator decides to accept the request. The user gets notified on email that they have been accepted to join, and they get added to the event attendee list.

Hope to be pointed in some direction, thanks
