Seeking Calendar Aggregator + Upload Ability

Hello,

I'm looking for a plugin of some sort that will support these three things ... does this exist? Any recs?

1. Event calendar that is visually appealing + has filter options where we can add our personal events
2. Way to aggregate existing events from various sources + approve them to be added to our event calendar (I don't want all of them)
3. Event submittal for anyone local who wants us to include their unique event - we have to approve to be added to the overall event calendar

Does this exist for Squarespace? TIA

I have also been searching for this for years but I have had no luck, I've tried using Zapier and other automaters and as well as third party apps like elfsight, tockify etc. but basically the only solution I have found is embed another service (like google calendar, teamup etc.) in squarespace which obviously doesn't really do what you're looking for

Following. Currently using a form on the website for visitors to upload events, which then appear in Google Docs. From Docs we have to manually add to the Events Calendar. Looking for a more efficient way to view and approve with auto-upload of information. Thanks for any suggestions.
