Durable Functions Monitor Instance History with user managed identity

[Prudhvi469]

I have an Azure Durable Functions app using .NET 8 Isolated Worker that throws the following error when trying to view a Durable Function instance's history:
"Failed to load tab. Unexpected response code, Expected:OK or NotFound, Received:Forbidden":

The function app have

• System-assigned identity
• Two user-assigned managed identities are attached to the Function App
• Only one of the user-assigned identities has all 3 required RBAC roles on the Storage Account: Storage Blob Data Contributor, Storage Queue Data Contributor, Storage Table Data Contributor

App Settings configured:

• DurableTaskStorageConnection__accountName

• DurableTaskStorageConnection__clientId (Have access to the storage account)

• DurableTaskStorageConnection__credential = managedidentity

• AzureWebJobsStorage__accountName = different storage account

• AzureWebJobsStorage__clientId =

• AzureWebJobsStorage__credential = managedidentity

host.json:

{
  "extensions": {
    "durableTask": {
      "storageProvider": {
        "type": "AzureStorage",
        "connectionStringName": "DurableTaskStorageConnection"
      },
      "hubName": "Hub"
    }
  }
}

Relevant .csproj packages (for .NET 8 Isolated Worker):

Given all of the above is configured and verified on a .NET 8 Isolated Worker Durable Functions app, what else could cause this Managed Identity authentication failure for monitor instance history, and what are the next diagnostic steps to resolve it?
