How can I switch to new resource-based settings in my theme?

Hello,

In theme setting documents, I found “legacy-resource-based-settings” notice.

https://shopify.dev/themes/architecture/settings#legacy-resource-based-settings

When I use product selector at my theme, it return handle, so this is “legacy-resource-based-settings”.

Can I turn to new(?) resource-based-settings my theme?

I always stuck with all_product limit. If product selector return ProductDrop, it really useful.
