Generate a PandaDoc embedded signing session so a document can be signed inside your own web app

Steps

1. Create the document normally (e.g., from a template) so it has at least one recipient.
2. Generate a signing session by calling the Create Document Session endpoint, specifying the recipient email and a lifetime — the response returns a sessionId.
3. On the client, install PandaDoc's embedded signing JS library and import its Signing component.
4. Instantiate the Signing component against a container element with the sessionId and a region option, then call its open method to render the signing iframe in the target container.
5. Subscribe to lifecycle events (e.g., document loaded, document completed, document exception) to drive your app's UI and post-completion logic.
6. Destroy the signing instance when the flow ends to release resources.
