Event calendar

Hey, I'm looking for a self hosted event calendar that I can share with a group of friends. Optimally the following things should work: tag events (location, type of event, ...) allows people to mark if they attend (yes/maybe/no) either by accounts or simply by sharing the link (maybe also additional text comments) allows other account to create events maybe add an image nice plus: allows people to directly import the event and details to their calendar I would prefer to run it as a docker container on my raspberry pi and then access/publish it over my domain. I looked at eventschedule, while the free version looks nice, it has some features I don't need (ticket sale, AI integration for event import). And I didn't see an option for people to say they attend or not. Does anyone know a fitting software? Thanks in advance.
