Hi Damian
While there are no native pop-ups or blocks allowing you to have it in your app, I think that it’s achievable with the Vibe Coding block. You just need to give it a nice prompt asking to check the created date of the user, and grab the events that happened after that date, and create a carousel or slides for those events as a modal in the center of the app during the initial log in process of that user, something like that. I believe that it should be possible.
To not spend much credits on prompting this, you can give a detailed information to some AI tools like Chat GPT or Gemini, and ask them to generate a nice prompt for you based on that info, which you can use to create a Vibe Coding block that would serve as a pop-up.
