IOT Hub (EventHub) supported Extensions

Question

Hi,
I've created a PowerShell Core v7 Function App and added an IOT Hub (Event Hub) Function. When I run it I get the following error:

Microsoft.Azure.WebJobs.Script: One or more loaded extensions do not meet the minimum requirements. For more information see https://aka.ms/func-min-extension-versions.
ExtensionStartupType EventHubsWebJobsStartup from assembly 'Microsoft.Azure.WebJobs.EventHubs, Version=4.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not meet the required minimum version of 4.3.0.0. Update your NuGet package reference for Microsoft.Azure.WebJobs.Extensions.EventHubs to 4.3.0 or later.

Reading the error says that the following article should fix the problem - https://github.com/Azure/Azure-Functions/issues/1987

I've added this into my hosts.json and this is when I get the error:

{
"version": "2.0",
"managedDependency": {
"Enabled": true
},
"extensionBundle": {
"id": "Microsoft.Azure.Functions.ExtensionBundle",
"version": "[3.3.0, 4.0.0)"
}
}

What am I missing here? I can't find any info anywhere other than this MS doc which says the same thing - https://learn.microsoft.com/en-gb/azure/azure-functions/functions-bindings-register#explicitly-install-extensions
