How to get data in conversation editor

Hi team,

I’ve been using the ticket_conversation_editor placeholder in my custom application. When I click the icon in the reply editor, a modal appears. How can I retrieve the content typed in the reply editor when opening the application from the conversation editor placeholder?

Thanks & regards,
Gopi
