With the use of shortcodes it is possible to react to the content by emojis.
So you install the plugin and create new emoji with a title an emoji itself, a count field and an initial count, to fake the initial value of the clicked emoji.
The shortcake is [emojized id=“8” count=“true”] (or false or empty)
In the new version you can limit votes to one per user.
This plugin demands WP REST API plugin.
It has the same approach as the plugin “Emoji Reactions”
https://wordpress.org/plugins/emoji-reactions/
but that seems to be discontinued.
So have fun with emojis.
