Where to find the category id?

While adding shortcode for single categories according to this –https://demos.welaunch.io/wordpress-store-locator/docs/topics/shortcodes/ you can specify a category id or multiple ids.

You will find the category IDs when you go to wp-admin > store categories. Then edit a category, look into the URL of your browser and search for “tag_ID=33”. 33 would be the ID then.
