How to add context menu item in Logcat and open by plugin with selected text?

Hi 

I am developing a format plugin that will format many languages. I created that toolbar component and If any text copied to my input Editor, it will format.

The problem was, I want to get an Action If I right click on Logcat window to open my plugin with selected text?

I am new to plugin development, and I didn't know keywords to search that?

Thanks in advance
