How to run if if else condition based on element visibility in selenium robot framework?

I am automating a user registration form flow, where successful registration shows a success message and any validation error throws alert text. For this, I am writing an if-else flow based on the visibility or presence of an element on the page. I will pass the control to a specific keyword with that condition

${SuccessBreadcrumb} is the element which is visible when the registration is successful

Code Snippet

*** Settings ***
Library  SeleniumLibrary

*** Variables ***
${SuccessBreadcrumb} =  xpath=//a[contains(text(),'Success')]
${SuccessMsgLocator} =  xpath=//p[contains(text(), 'successfully created')]
${AlertMsg} =  xpath=//div[@class='text-danger']

*** Keywords ***
Verify Validation Message
    [Arguments]  ${UserDetails}
    sleep  2s
    run keyword if  ${SuccessBreadcrumb}  is visible  Keyword 1
#   ...  else  Keyword 2


Keyword 1
    [Arguments]  ${UserDetails}
    ${AccountCreatedText} =  get text  ${SuccessMsgLocator}
    should contain  ${AccountCreatedText}  ${UserDetails.ValidateMsg}  ignore_case=true

# Keyword 2

Error Log
