Calendar vs Full Calendar Plugin

What I’m trying to do

I want the ability to view existing events and create calendar events in my Apple / Calendar app from within Obsidian.

I am using a Vault structure provided by Tony Ramella. It uses the Calendar plugin. I assumed – incorrectly – that this plugin would allow me to create and view calendar entries in my main calendar (Apple Calendar) but it doesn’t.

I assumed that the Calendar plugin would allow me to view and create calendar events but it doesn’t. I believe the Full Calendar plugin will allow me to create and view calendar events from withing Obsidian but I don’t want to break the Tony Ramella Vault by installing the Full Calendar plugin.

If I install the Full Calendar plugin, will it play nicely with the Calendar plugin?

Can I configure the Full Calendar plugin to do what the Calendar plugin does AND also allow me to view and create calendar events from within Obsidian?

Thanks for any help
