Emoji based feedback submission and data retrival

I am building a emoji based feedback form for blog posts, something similar to facebook.

Figma design :

I understood the first part of building it from here : How to make rating scale with emoji? - #3 by Vlad_Belov

For second part, I want to retrieve the count, so if a person clicks on “like”, I want the form submission to go, and then retrieve it and show the increment.

What are my options for implementing it ?
Does it need a backend or a database functionality ?
