@nobodyinperson there is a app-in-chat option, #WebXDC maybe some sample app fits this purpose? https://webxdc.org currently only implemented in #DeltaChat .
@adbenitez
sorry, I missed your reply at the time. Great to know #webxdc has traction!
@nobodyinperson
@tetrislife @nobodyinperson not only #DeltaChat, Cheogram (#XMPP client based on Conversations) also does support #WebXDC
