Javascript for checking the version date of a form compared to one on the intranet

I am new but learning javascript and its use in Adobe Acrobat Forms. My version of Acrobat Pro is continuous release 2023. This is a hefty order but curious to see if it can be done.

I will create a button named "Check version date" with javascript action to pull a date from a hidden field on the form housing the version/revised date of the form.  i.e. this.getField" ("VersionDate") Then, it gets super tricky. I want further javascript language to:

• Go to a URL intranet link of the same form and check the date of that version.
• Return an app.alert with validation, "This is the most current version of this form, please proceed" or "You are not using the current version of this form, please go to intranet and download the newest copy" 
• Possibly add a reject notification after form submit if it is the wrong version

Overall goal is to have the check version button at the beginning of the form before users complete the form. Then, have the end user confirm they have the most recent version of the form compared to the form published on SharePoint intranet site. Users are constantly using shared or previously downloaded HR forms which creates larger issues. This way my forms will let them know a new version is available on our intranet. Providing instructions with a caution sign on the form to always get a new copy from the intranet is not being followed. 

Any help towards this tall order is greatly appreciated.
