Peaka `co.huggingface.ramamatar/peaka` Initializes an Embedded Peaka session and returns a session URL that can be used to embed the Peaka UI in an iframe. [Embedded Peaka](https://docs.peaka.com/embedded-peaka/introduction) allows you to integrate Peaka's data management capabilities — including connections, catalogs, caching, queries, and a full UI — directly into your application. The returned <code>sessionUrl</code> should be loaded inside an iframe. For security, direct iframe embedding requires enabling "Embedded UI" in Developer Settings and registering your domain over HTTPS. #### Configuration options - <code>theme</code> / <code>themeOverride</code>: Customize the look and feel of the embedded UI, including custom CSS theming. - <code>featureFlags</code>: Control visibility of UI sections (e.g., enable/disable queries, connectors). - <code>sessionMode</code>: Choose between <code>FULL_STUDIO</code> (complete Peaka experience) or <code>CONNECTOR_MODAL_ONLY</code> (streamlined connector setup). - <code>connectorType	`request_body`	Not stated
