Vertical slide in Figma Slides

I want to create a presentation in Figma, but I need it to be vertical. I’ve been trying to figure it out all morning, but I still can’t find how to make a slide vertical in Figma Slides.

Also, I’d like to ask: is it possible to make a clickable word on one slide that links to a specific slide in the presentation?

I usually work in Figma Design, and now in Figma Slides I feel a bit lost.

I’d really appreciate your help!
