I’m making the switch to using Neomutt for my email, but I still have calendar data from several accounts I want to access locally. Is there something like neomutt, but for calendar data? Maybe an Obsidian plug-in, or some other OSS app I can configure?

I’m using EndeavourOS (Arch), with the Sway DE, and would prefer staying away from KDE/Gnome based apps.
