How to make the dynamic countdown that takes time input from editor

Hi everyone,

I was building a minimal theme, which has the countdown(counter) present in one standalone section(use attached below). And what I want is I want to make it dynamic, Dynamic in a sense, the time to be set from the builder. How can I achieve that?. As for now, what I am doing is I am giving the time while building the theme which is creating the issue of adding the multiple themes if I want to change the time.

And I know that there exists the countdown component in the mautic, but I want to use this custom countdown. And I have more issue which I will add once this issue is fixed. Thank you in advance :blush:

Can anyone please help me to figure out the actual solution? It would be great help for me. Thank you :blush:
