JIRA link

https://hee-tis.atlassian.net/browse/TD-4340

Description

I check if SectionContentData is not null and check the count is more or greater than 3 to ensure it is not a new request,
I return SectionContentData for the multiPageFormService to prevent the user selecting the tutorials again

I have:

• Run the formatter and made sure there are no IDE errors (see info on Text Editor settings to avoid whitespace changes)
• Written tests for the changes (accessibility tests, unit tests for controller, data services, services, view models, etc)
• Manually tested my work with and without JavaScript
• Tested any Views or partials created or changed with Wave Chrome plugin and addressed any valid accessibility issues
• Updated/added documentation in Confluence and/or GitHub Readme. List of documentation links added/changed:
  • doc_1_here
• Updated my Jira ticket with information about other parts of the system that were touched as part of the MR and have to be sanity tested to ensure nothing’s broken
• Scanned over my pull request in GitHub and addressed any warnings from the GitHub Build and Test checks.
