The "Wait" block allows you to pause the conversation for a certain amount of seconds.
This can be useful if you want the bot to emphasize on what's been said or to wait before a redirection for example to make sure the user has read everything.
This should be used wisely. If you want the bot to write slower or faster in a more general sense, you need to check the Typing emulation settings
Pause the flow
You can enable the "Pause the flow" option if you ever need to mark a pause in the flow.
Under the hood, typebot always compute all the blocks between each input blocks. But sometimes you may want to display some messages before a long-running action like a slow webhook request.
