Hi everyone,
I tried using maxPrompts with System.Text component and expected it to restrict the number of prompts. To my surprise, it didn't work.
Attaching the screenshot and the BotML here. Please suggest changes if any.

BotML:

states:
  resetCountry:
    component: "System.ResetVariables"
    properties:
      variableList: "greeting"
    transitions: 
      next: "readCountry"
  readCountry:
    component: "System.Text"
    properties:
      variable: "greeting"
      prompt: "Please enter your country:"
      maxPrompts: 3
    transitions:
      actions:
        cancel: "nomatch"    
      next: "matchCountry"

  matchCountry:
    component: "System.MatchEntity"
    properties:
      sourceVariable: "greeting"
      variable: "country"
    transitions:
      actions:
        match: "textOutput"
        nomatch: "resetCountry"
  textOutput: 
    component: "System.Output"
    properties:
