How to get topic link in theme level

Permalink
I want somehow to use "getTopicLink" function from the "topic list" block without adding this block (i only need to print the name of the topic in my blog entry + this name should be clickable)

Some page with topic "categoryA" selected.
<?php
   $topics = $c->getAttribute('topics_handle', 'display');
   echo $topics; 
?>

This code return "categoryA" but i also want "categoryA" to be clickable.

In topic list block -- controller.php i find this function - thier is some way to use this function in "theme level" by code?
public function getTopicLink(\Concrete\Core\Tree\Node\Node $topic = null)
..rest of the code


** Of course i can add custom template of the "topic list" only showing the name+link - zero extra design (but this is little weird)
