How turn on the "on this page" TOC

[talwgx]

UPDATE: It was only after I read https://github.com/ankitskvmdam/clean-jsdoc-theme/issues/231 That I understood that on my Mac laptop, the TOC was indeed being rendered, but the screen was not enough to show it. I do believe issue #231 is important as w/o reading it, I would have never known as a user that a right-hand side TOC was even being rendered , which it was and only became visible when I zoomed Chrome out to 75%. Here are screenshots:

75% resolution

80% and up:

In this demo image, the table-of-contents is turned on the right, but on the actual demo page it is not, and that is also the behavior I see when I run jsdoc+clean locally on either my code or the demo code. I'm sure I'm missing something obvious, but I wondered if/how you turn on the right side "on this page" TOC for this template? I apologize for the basic question and very much appreciate the help!
