How does HTTPS work with react native after deploying?

I would deploy my Node/Express API Server to Heroku. From there I get the SSL Certificate automatically.

But do I have to do something on the client side (React Native App) that the connection uses the httpS protocol? (encrypted data traffic?)

Here is my Old Post, but nobody answered.. 🥲

React Native - Authentication - Prevent Token / Cookie being stolen / sniffed? #man in the middl #encrypt data? SSL / HTTPS?
