.NET 8 Custom Code support for Azure Logic Apps (Standard): is it supported on Mac OS / ARM64 platform?

[demiliani]

I'm using Azure Logic Apps Standard extension in Visual Studio Code on Mac OS Sequoia for creating a Logic App with .NET 8 Custom code (see https://techcommunity.microsoft.com/blog/integrationsonazureblog/announcement-introducing-net-8-custom-code-support-for-azure-logic-apps-standard/4167893).
Project (Logic App + .NET Function) is created and compiled successfully. But I'm not able to open the integrated designer.
Error in VS Code is this:

It seems that the .azurelogicapps/dependencies/FuncCoreTools is always empty. Azure Function Core Tools are successfully installed on the system. Anyone can confirm is this works on Mac OS or on Windows on Arm or not? It works correctly on Windows 11. Thanks in advance.

Trying to create a standard logic app workflow as described here: https://learn.microsoft.com/en-us/azure/logic-apps/create-standard-workflows-visual-studio-code does not work on Windows 11 on ARM either:
