Adding a sidebar in Kavana theme

I am having a terrible time adding a sidebar to my pages with the Kavana theme so I can add widgets. I have tried several different plugins and none of them will add a sidebar.

I noticed in my posts that the sidebar is just a column with different blocks. Does Kavana not support sidebars? I am very confused because I see that there are sidebar templates in the Editor but I don’t know how to turn those templates into pages.

I have watched around 10 youtube videos and have spent weeks reading in wordpress about the different features but nothing is helping me.
