Follow these steps to give the workflow the necessary permission: 1. Go to the App Registration connected to your workflow in the Azure portal. 2. Go to API permission and press Add a permission. 3. Press Microsoft Graph --> Application permission. 4. Choose the permission GroupMember.Read.All and press Add permission. 5. An admin of your Azure tenant must give admin consent in order for the permission to start working.
