Shopify App - how to install SLL Certificate

[PenguinDev]

Hello,

I'm new to developing apps on Shopify. I've just created my first app and set it live on a Linode server using docker, which I can access, and I've also configured a DNS. However, I need help installing an SSL certificate to make the app live. Could anyone explain how to do this? My app is built with Remix.js.

I have already requested my SSL certificate with certbot.
