Use GoTo option following gupshup documentations to go from state (user select option to return to main menu). I get the following warning message. "The selected node has user child states. If you select this state, your bot will wait for user inputs to continue the flow".

and it is not working as expected, and we want to show the main menu to user again.

Goto works differently. If you want to execute a certain bot-state, you need to go-to to that state's previous state.
