How can I display subscription prices on collection page in my theme?

Displaying this price on your collection pages can be done by our app only if you also have the add to cart button there and the HTML form element. Without that, you can simply ask your theme developer to adjust the theme in a way that the theme will show the lowest subscription price in there. Shopify has a great documentation on how to access the subscription prices from product here: https://shopify.dev/docs/storefronts/themes/pricing-payments/subscriptions/add-subscriptions-to-your-theme
The thing is that the subscription prices from our app are available on the product object in your theme, so that your theme can use it and display it on it's own.
