Taxonomies Category Page

[pik10]

I created a taxonomy called categories in the Hugo.toml configuration file.
[taxonomies]
category = "categories"
tag = "tags"
series = "series"

I want to see a list of categories that are used in the front matter content.
One page has categories = ['Aviation'] in the front matter
Another page has categories = ['Aviation', 'Aviation Weather'] in the front matter

When I go to my website url example.com/categories it is not showing the categories that I created.
When I go to example.com/categories/aviation or example.com/categories/aviation-weather the page is showing pages that have the aviation category.

I think I figured out the issue. The paper theme doesn't have the terms.html template. I added the terms.html template to the theme and the terms are showing.
