The Clams Browser App is already integrated into Sovereign Stack as seen here.
Connectivity
The next piece of the puzzle is to expose the experimental websocket port on core lightning and expose it to trusted devices (via IP whitelist) in a manner similar to this repo. This will also be required for the Lightning Prism functionality.
Features
It is expected that Clams will provide the UI for installing and managing core lightning plugins. reckless is a core lightning API facilitating the lifecycle of various ecosystem plugins. Sovereign Stack deployments should ensure that the core lightning docker image deployed under BTCPay Server has everything it needs for remote clients to successfully execute the reckless plugin and load popular plugins
