Ah, I missed this is still open. I bumped dialogs in #10821 So make sure to rebase and retest :)

Before I move further, we should migrate the duplicate session dialog to NcDialog too, right?

https://github.com/nextcloud/spreed/blob/main/src/store/participantsStore.js#L790-L825

It will be replaced by an event emission from the store and listened by the main components calling 'joinConversation' :

App.vue
FilesSidebarTabApp.vue
PublicShareAuthSidebar.vue
PublicShareSidebar.vue

For the others, like LeftSidebar's function call, we can use the NcDialog in App component instead

Lets do that in a different PR. It's a more problematic thing to check and test than the currently handled deletions.

I would use error in all cases like you used already for the breakout room deletion
