Okay, I was able to find the right panel part. However, what I was looking for I just got a tip from the Discord group. There is a small button in the lower right hand corner - press AND HOLD that and you will get a menu showing you the buttons that normally appear on the left hand edge of the desktop app.
I thought the button was a “touch” but I had to hold it a LOT longer than I expected for it to work on my iPhone.
Oh - sorry, I completely misunderstood, I thought you were looking for the right-hand sidebar like I was.
I see what you mean, thank you. Press and hold brings up a menu to open quick switcher, graph view, daily note, or command palette, or insert template or manage workspaces. Whichever you select will be what comes up when you just tap the button then.
