Thanks Jorge! We coded the chat tool ourselves (please see Simple chat application).
We have also made a more sophisticated version that is showcased in this video: RAFO 2021 -ohjeistus - YouTube
Everything unfortunately in Finnish. In short we added:
- Registration and automatic digital business card generation by registration details
- Sending / receiving business cards and instant viewing of the ones received
- Custom chat rooms / 1-on-1 chat rooms
- List of participants (that naturally generate into leads)
If you want any more technical info, then @Jumbe is your man.
