I am setting up my first Einstein Bot. In the setup steps it says "If you want to connect your bot to your chat implementation, select Web Chat for the channel and select the chat deployment you created for your bot. If you want to connect your bot to your Messaging implementation, select the messaging channel type (for example, Text), and then select the channel name as the deployment." What is the difference between connecting the bot to a chat implementation versus connecting it to a Messaging implementation? Is there a difference? What do you recomomend? I don't really understand what a chat implementation or messaging implementation is to begin with... :) Thank you for your help!!
