In some cases, you will want users to immediately land on a Carbon workspace when accessing Foundry; in other words, for a Carbon workspace to be the user home page in Foundry. To configure this setting for your entire organization, go to /workspace/control-panel and navigate to Platform experience in the left-hand panel. If you wish for users to land on their default workspace, set the Home page URL configuration to /carbon.
If you wish to configure this on a more granular level and control which page specific groups of users land on, click New home page URL.
