How to declare that my app can open RSS Feeds?

I am building an RSS app and not sure how to configure the app to appear in the share sheet so I can open RSS feeds from other apps.

For example, if I open an RSS feed in safari it shows a popup asking if I would like to search the app store for apps that can open that feed. How do I make my app appear as an option to the open the feed? I am assuming this is done with App Extensions on iOS but I have not been able to find the relevant Solar/Corona documentation to explain what settings I need to set and how that process would work.

Can anyone point me in the right direction for how to make this work in Solar2D?

Thank you,
