MW Taxonomy includes a widget Custom Taxonomy List for presenting taxonomies in the blog. You need to use a theme that supports widgets for this, that is a classic (non-block) theme. Use the plugin <a href="https://wordpress.org/plugins/classic-widgets/" rel="ugc">Classic Widgets</a> if you don’t find the widget.
Taxonomies can also be presented by Tag Cloud widget or menus (classic theme).
