How to add a class for anchor tag for particular view using pager.html.twig?

Question

I have been trying to add class for anchor tag, but I could not find the right way to achieve this.

I want to add class for particular pager in view. There is no pager.html.twig for particular id.

I have already enabled the twig debug in services.yml . Its not showing any suggestion

Can I try in preprocess_pager() ?

Please some one help me to achieve this !
