Hi @Youcef, Marc (Luxembourg) ,
Welcome to Microsoft Q&A Platform. Thank you for the question.
If you want to develop workflows using the Logic App (Consumption) resource type, and your workflows need to use private endpoints, you must create, deploy, and run your logic apps in an ISE. For more information, review Connect to Azure virtual networks from Azure Logic Apps using an integration service environment (ISE).
If you want to develop workflows using the Logic App (Standard) resource type, and your workflows need to use private endpoints, you don't need an ISE. Instead, your workflows can communicate privately and securely with virtual networks by using private endpoints for inbound traffic and virtual network integration for outbound traffic. For more information, review Secure traffic between virtual networks and single-tenant Azure Logic Apps using private endpoints.
Regards,
Kamlesh Kumar
