I deleted my palette trying to make a dialogue. How do I get it back

I was making a dialogue and didn’t know what I was doing. Not knowing I was going to need the palette later, I deleted it with out thinking it was important. Now that I need it, i can’t get it back, and I’ve tried getting a different widget blueprint, but the palette still isn’t there. How do I get it back. Please help!!!

You mean the “window” palette? All of them under “window” menu.

I don’t have a windows button. Is it cause I’m on 4.9.2?
