Which type of document generation occurs asynchronously in OmniStudio Document Generation?

In OmniStudio Document Generation, the type of document generation that occurs asynchronously is server-side generation. This process is designed to handle the creation of documents in a way that does not block the user interface or prevent other processes from executing.

When server-side document generation is initiated, the request is sent to the server, allowing the client to continue operating and not waiting for the document to be generated. This is particularly advantageous in scenarios where document generation might take some time, such as when large volumes of data are involved or when complex templates are being processed. As a result, the end-user experience remains smooth and uninterrupted, enhancing productivity and efficiency.

In contrast, client-side document generation happens immediately within the user interface and may not be suitable for larger or more complex document tasks, as it can lead to delays or a lag in responsiveness. Checklist items do not pertain specifically to asynchronous document generation; they are more about managing tasks or elements within the process rather than the method of generating documents. While it may seem that all types could occur asynchronously, only server-side generation is designed to be efficiently handled in this way, making it the correct answer.
