Automation to add event participants to subscribers with opt-in checkbox

I want to provide an opt-in for wix event participants to add to our subscribing list. Right now, only wix-form or wix-booking has this feature, but not wix-event?

Any work around?

I need to send registration email, post-even email, and adding the opt-in to the subscriber list. Want to know how to do automations with all these. Should be possible if wix-event has the opt-in box, but currently doesn’t or I can’t find it.

Any pointer is deeply appreciated. Thank you.

I have the same issue. Have you found the answer?

I have the same issue - how to subscribe event participants?

I can neither
a) add the checkbox to the registration form
nor
b) change subsciption status via automation

The only way currently is csv import of participant list - but then I do not have proper DOI
