Playground with hmr for a nuxt module which contains scss

in my module, I import style with "nuxt.options.css.push(resolve('./runtime/assets/index.css'))" and also "import('../assets/optionalStyle.css')" but these files are scss files compiled, and so I have problems when I try to launch a playground to test my module with hmr because it tells me that it can't find the css files, logical since the scss files are not compiled (and I don't think I want them to be compiled at that time to have hmr on the style too), how can I solve my problem?
