Add support for comet chat

Is your feature request related to a problem? Please describe. New comet chat block to integrated cometchat functionality into typebot

Describe the solution you'd like Add ability to launch comet chat widget from Typebot flow to chat with a group or individual, similar to Zendesk block

Describe alternatives you've considered Other option is to consider building a cometchat app in Typebot to directly allow chat within a chat flow instead of launching the widget. This is a good phase 2 to add.
