My side bar is gone

So um, hi, don't know how I got here, but I did. So in Musescore when I try to add accedentals or words, that side bar is nonexistent, and I have no idea what I did or what happened to have it disappear on me. Any way to get it back?

I have no idea if I hid it or got rid of it, but I don't know what happened, and I'm seriously needing it. Please help
