IF ELSE in robot framework [Keyword as a condition]

I just can’t figure out how to map a keyword as a condition.

    @keyword("Is the Closed Message Page Present")
    def check_closedMsg_page(self):
        result = self.CLOSED_TEXT.is_displayed
        self.LOG(f"It returns {self.CLOSED_TEXT.is_displayed}")
        return result

The above function returns a bool value either True or False.

“Is the Closed Message Page Present” is a keyword which I want to make condition. If the condition is true then it should execute the below two keywords else skip it.

    IF  Is the Closed Message Page Present = True
        Then Login      username        password
        And Close Browsers
    END

I tried following:

IF  Is the Closed Message Page Present == 'True'
        Then Login      username        password
        And Close Browsers
    END

IF  'Is the Closed Message Page Present' == 'True'
        Then Login      username        password
        And Close Browsers
    END

Is the Closed Message Page Present
IF  True
        Then Login      username        password
        And Close Browsers
    END

I am expecting the keyword (Is the Closed Message Page Present) to be condition which needs to be true to execute the other two statements or keywords.

Answer

I’m still new to the framework, but the only simple method I found is to store the keyword return value to a local variable and use that in the IF statement.

*** Settings ***
Library  SeleniumLibrary
Library  ../stackoverflow.py

*** Test Cases ***
robot Example

  ${value}  Is the Closed Message Page Present
  IF  ${value}
        Login      username        password
        Close Browser
  END

*** Keywords ***
Login
  [Arguments]    ${username}  ${password} 
  log  'Logs in to system'

stackoverflow.py returns a random True/False value

import random
from robot.api.deco import keyword

class stackoverflow:
    @keyword("Is the Closed Message Page Present")
    def check_closedMsg_page(self):
        return random.choice([True, False])
