Adding a button to message menu


Hi there! I want to start developing a plugin/app? for RC to make an integration with Q2A where the user can select the messages which will be converted into questions, and then the messages which will be the answers to that previously marked question.

To accomplish that I thought of adding buttons to the message menu, but I’m not sure what approach should I take to modify the interface. In the documentation I can’t find something like extending the UI.

The option of using slash commands is not feasible, I need something more user friendly.

Thank you in advance
