Maybe there is a way to already do this, that I missed in my limited search. But I am really pleased with how beorg syncs with Reminders/Calendar to display relevant information on the agenda screen.
However, beorg has spoilt me with this feature, and I now wish that information showed up on the agenda in my laptop too. That would be possible with beorg wrote whatever it was displaying from reminders/calendars to lets say inbox.org
This isn't currently an implemented feature. One option for now could be to create a Shortcut which pulls in all your reminders and upcoming calendar entries and creates an org file. There are certainly some Emacs packages which can sync a calendar to an Org mode file which may also be worth looking at.
