How do I set up the slider in the grid in Grid 2?

I can see how to set up a slider outside the grid. My problem is in setting up a slider in the grid/ banner area in Grid 2. On the example of grid 2 it shows a slider with two images in the grid at the top of the website so this must be possible. When I go into “banner” in UX builder and click on each element suggested there (image, texts etc) this all works fine but the slider facility does not appear here. I can add a slider elsewhere but not in this grid. When I go into video guides I get examples of how to set up sliders but not within this grid. When I follow any examples that I’ve seen I end up with a slider elsewhere, but not where I want it. Can anyone please help me with this?
