When using an embedded URL, there are no limitations. Anything supported in Storybook will appear in DSM.
When using the CLI-based integration, DSM supports Storybook 4.x through 6.3. The CLI-based integration does not yet support stories written in the new MDX story format that was introduced in version 5.3.
