Whoever had experience with implementing / or integrating 'tags' cloud 

OR
user mentioned 'tag' like functionality using any 3rd party plugin, please share your expertise.

Use-case: the user is landing an article with 1k comments -> pressing any tag button e.g. 'sunroof' -> only comments containing 'sunroof' are loaded.

Example/Demo: https://ibb.co/18ZvH3L

p.s. Appreciate it has sort of intersection with the "search" plugin + but just wondering if any of the experts had any other approach to tackle this.
