I'm looking to use Draw.io to create some process maps. I can see from tutorials / other posts on this forum that I should use the Container Shape, under General Shapes, in order to get a swimlane. However, that shape does not appear to be available to me. Is there something additional I need to do / install to get that shape?

Many thanks!
