Tabs with SwiftData

Hello folks, absolute newbie here.

I'm following a tutorial that I'm trying to adjust to my own needs. In the tutorial the app is sat up in a way that you can add a new entry to a note taking app by tapping on a button which brings in an edit view.

What I'm trying to do is to bring in the edit view by adding it as a tab on the bottom instead.

Here's my ContentView:

import SwiftData
import SwiftUI

struct ContentView: View {
    
    let example = Entry(content: "Example Entry")
    
    var body: some View {      
        TabView {
            LifeEventsView()
                .tabItem {
                    Label("Life events", systemImage: "house")
                }
            EditEntryView(entry: example)
                .tabItem {
                    Label("Add new event", systemImage: "plus")
                }
            MattersView()
                .tabItem {
                    Label("What matters", systemImage: "house")
                }
        }
    }
}

#Preview {
    ContentView()
}

And here's the EditEntryView:

import SwiftData

struct EditEntryView: View {
    @Bindable var entry: Entry
    
    var body: some View {
        Form {
            TextField("Entry", text: $entry.content, axis: .vertical)
        }
        .navigationTitle("Edit entry")
        .navigationBarTitleDisplayMode(.inline)
    }
}

#Preview {
    do {
        let config = ModelConfiguration(isStoredInMemoryOnly: true)
        let container = try ModelContainer(for: Entry.self, configurations: config)
        let example = Entry(content: "Example Entry")
        return EditEntryView(entry: example)
            .modelContainer(container)
    } catch {
        fatalError("Failed to create model container.")
    }
}

The build succeeds but I get an error while running saying: Thread 1: Fatal error: failed to find a currently active container for Entry

I'm sure this is an easy fix but I've been thinking with it for a while with no luck.
