Why is there no scroll bar in XD? What is the best mouse to use?

I have been using XD for 1.5 years now and I am perplexed why there is no scroll bar to navigate up and down, side to side in XD. Is there a setting that I am missing? How do I get a scroll bar on the side and bottom of XD?

Example: I am creating many webpages in XD and I want to zoom in and out frequently to work on copy, then go to another page. Or just scroll up in XD, but I can't! I have to go to View >Zoom to Fit All then zoom to the point I need to go.

Also, what mouse does everyone use to design in XD? I like ergonomic wired mice, and I like the old Apple Might Mouse specifically because it has a scroll BALL that can zoom and move in any direction in XD. I don't like wireless mice because I hate having to change the battery every month (eco and convenience reasons).
