How to make new modules accessible to Web GUI Module dropdown

[jdubp]

I don't see anything in the documentation, but how do modules become accessible in the Web GUI interface?

For instance the misp module is only accessible via the CLI (either viper-cli or CLI in viper-web) and any new modules I add in modules are also only accessible via the CLI. How can modules new modules be made accessible via the Modules dropdown in the Web GUI and not just CLI?
