Is there a possiblity to reduce the build size ??

ALso, Since it's component chaining, I am not able to import Individual components either.

@shriDeveloper Actually, we tested both polaris-vue and Shopify ReactJS version, but we see that the components cannot be imported fully individually.
As you said, it's chaining, the components are linking together. So I doubt its bundle size only can be reduced a little bit, compared to full library import.
